🐰🐤Roro, Dodo & Kiki:How to Move a GIANT Rock! 🪨Added:
Wow, it's hot. Yes, but look, the forest is cool. I smell something down by the river.
It is a very bright and hot day in the tiny forest.
The sky is a perfect clear blue today.
I've never seen it so bright.
We have to get going.
Quack quack, it is so warm my feathers are toasty. I'm glad you're here.
Finally stopped moving. All right, team.
Let's keep moving. This way, I see some Meow. The summer sun is truly strong today. I agree, but we'll manage. Yes, teamwork.
The water will be the best place for us.
>> [laughter] >> Let's visit our friends by the river.
I hope we can splash and play all day.
We definitely will, as soon as we find them. Look, there they are.
It is a perfect day for a river adventure.
The shade feels much better already.
Quack. Quack.
I agree.
Look, the river is sparkling. Wow, it's so pretty.
Let's go closer.
We are here. It's so peaceful. Quack quack.
Meow.
>> I don't know if we'll ever get home. Me, neither.
Squeak.
Oh, dear.
We've searched everywhere.
It's just too hot out here. Don't worry, Ollie. We'll help you find a way to cool off.
What is wrong, Toby? Why are you not swimming?
You both look very unhappy.
Wiggle.
Weary.
A big, heavy rock fell in front of our cave. We cannot get inside to take our nap. I know, but we'll help.
Let's think of something. Yeah.
We are stuck out here in the heat.
We're here to help. We'll get you out of there. Really?
Quack.
Look at that giant thing.
That rock is huge.
It's bigger than us.
Hmm.
Meow. It is stuck very deep in the sand.
We'll help you, Toby. Maybe I can push it.
I I can't move it.
You okay, Toby?
Don't worry, we'll help.
Let's think this through. Oh.
Woah. Squeak. I am stuck.
HELP, I'M STUCK.
HMM.
Just a moment.
Let me help you up, Toby.
Thank you, Kiki.
Oops. I am okay. Thank you, Kiki. You're welcome, Toby. We're here to help you, Ollie. Thanks, Dodo.
>> [laughter] >> We cannot move it just by pushing.
But we can use the science of the lever.
Quack quack. Meow. Squeak. Squeak. We'll build a lever to move it. A lever?
Is that a type of magic wand? No, silly.
It's just physics.
It is better than magic, Ollie. It is physics.
If we have a strong stick and a fulcrum and with teamwork, we can lift even the heaviest things. Oh, wow. Let's begin.
Meow.
A lever helps us move a big mass.
>> [laughter] >> It is all about the balance of power.
Quack quack quack. Let us find the tools. The great rock rescue starts now.
Let's split up. Quack, quack.
I'll check the log.
Find a tool, any tool. Quack.
Quack.
This one looks very strong.
It did not break when I sat on it.
Oh, I hope this works.
I will help you pull it.
>> [laughter] >> The little This is heavy. But we can do it.
>> [snorts] >> Almost there, Ollie. Keep pushing.
We're doing it, Roro.
Look, there they are.
Oh, no, they're trapped. They need our help.
Excellent work, team. That branch is perfect.
Woo.
That was a workout.
But I am ready for more.
I know you are, Roro. We're here for you. Now, we need a fulcrum, a strong point to rest our lever on.
Meow.
How about that round stone over there?
This one looks solid and stable.
Yes, Kiki. This will be the perfect heart of our lever.
Meow.
Together. Almost there. One, two, three.
We did it. Look.
Ready for the log. The fulcrum is in place.
Now we can lift it. Be careful. We're ready, Toby and Ollie.
We put the branch over the small stone and under the big one.
Now, let's lift together.
Oh, no. Toby can't get out. Don't worry.
We're here to help. Let's look closer at this rock.
>> [screaming] >> Hmm, it's a tight fit.
Just a little more. Keep pushing.
Just a little further. Almost there. We did it.
It's under.
Just a little more.
Push.
Quack, quack. We can do it. The lever is set.
We can do it. Ready when you are.
Let's go.
I wish we were home. It looks like a giant seesaw.
We can make it work. Yes, together we can. We all need to push down on this end at the same time. Quack, quack.
Let's do it.
I'm ready. Let's do it. We're here to help.
We'll figure it out, Toby.
I am in position.
Looking good, Kiki.
Oh, they're ready.
I hope it works.
Good luck, everyone.
On the count of three.
Three.
One.
Two.
Three. Three.
Two. Two. Two. Two.
Almost there.
Keep going.
Three.
We need to push the rock. Look out. Yes, let's go. Keep pushing. It's bending.
We're almost there. Toby, Ollie. We're here to help.
It's moving. It's moving. Yes, it is.
Keep going, Toby.
Almost there. Oh, no. It's sinking too fast. We have to do something. Don't worry, team. Together, we can find a way. LOOK OUT.
WOAH.
>> [screaming] [screaming] >> OH, NO. IT'S QUACK.
MHM. That was not part of the science.
Oh.
It didn't work.
No, it's falling. Move. Move.
It's too big. We failed.
Now what?
>> [whistles] >> Are you okay, Roro?
I'm okay. Just a little bit chocolate colored now.
Meow.
That was a very slippery failure.
The ground is too soft here.
The fulcrum needs a solid foundation.
Without friction and a dry base, the lever will always slip. Quack, I get it now. Interesting friction. That's right.
Slip.
Does that mean we can't save our house?
Don't give up, Ollie. We just need to adjust our plan. We can do this.
Hmm, let me see. I have an idea. Oh, really? Tell us.
Yes, what is it?
Look.
Dry sand and flat stones.
We can use the sand to soak up the mud and the flat stones for grip.
Quack, quack. Meow.
Smart thinking, Dodo.
That will create the friction we need.
Let's get to work.
Round two is going to BE A SUCCESS.
SAND COMING RIGHT UP.
WOO, got it.
Here I come with the sand.
Perfect, Roro. Now we can start. Out of the way.
Sand delivery.
Don't spill it, Roro.
Hurry.
Why yeah.
>> These flat stones will provide the perfect grip.
Mhm.
This one is very sturdy.
Mhm.
We need to make the ground as hard as possible.
Look, it worked.
The mud is strong. We did it. That's it.
Keep it coming.
Quack, quack.
Now it feels solid.
Check. One stone here and another one there. This fits perfectly. Now, secure this piece. Good, one more.
I found a big one.
Is this enough?
Let's see. It's perfect. This foundation won't move an inch.
Woah, who are you?
Hi there. Are you okay? I think we can move it together. Look.
Careful, let's observe. Do you need some extra muscles?
Quack. A new friend. Yes, please.
We are trying to move this rock. Welcome to the team.
Thanks. I'd like to help.
I am small, but I am very fast.
On three. 1 2 3 Push. Keep pushing.
DONE IT.
WE DID IT. NOW TO HELP Toby and Ollie.
Yay! Stone stack. Let's find them. It's steady. This time it will work.
We must keep the lever dry so it doesn't slip.
The log is clean. Let's start.
Quack quack.
Ready.
Let's do this everyone. Ready. Lift.
>> [screaming] >> There.
The angle is much better now.
All right team, let's pull.
Ready.
Heave. Everyone get a good grip. Let's do this.
Ready.
I've got it.
Just a little more. I see it.
This rock is going for a ride. Oh, I hope so.
We can do it.
You can do it. I believe in you.
Yes. We know you can.
Go. Go. Go.
We push together.
One heart, one goal.
The sun is setting. We need to help him now.
Quack, let's go.
>> [screaming] >> I see a way up. Ready? And one.
Quack, quack.
Meow.
Two.
Alette, three.
Alette. We did it. We did it.
Heave.
Oh, no, the branch.
IT'S GOING TO SNAP. WE HAVE to do something.
I'm scared.
It's moving.
It's really moving. Don't stop. Keep going. Almost there. We did it.
Hooray.
The rock is moving.
Look at the cave.
We did it.
My cave.
I can see it.
The branch is breaking.
One big push.
We're okay, Toby, Ollie.
Don't worry, we'll get you home.
Together.
Now.
Keep pushing. Almost there. One big heave.
We did it. Hooray.
The rock is overthrown.
>> [screaming] >> Yeah, WE DID IT.
WOAH.
LOOK AT THAT.
OH, WOW. We actually moved that giant mountain of a stone.
Thank you, friends. Let's go home now.
It's open. IT'S WIDE OPEN.
>> [laughter] >> ALL RIGHT, FRIENDS. The cave is waiting.
Quack, quack. Let's go help them.
Wait for me, Toby.
Thank you.
I'm going in to check our beds.
Take your time, friends. We are so happy for you.
Quack. Meow.
We made a great team today.
We certainly did.
Meow. Science and teamwork never fail.
The wood is splintered, but we can fix this.
Quack, yes we can. We have to be precise. Toby, let's rest for a moment.
That was hard work. Quack.
Meow.
The air feels so much cooler by the water.
Hey guys, look what I found.
WHAT IS IT?
>> [screaming] >> LOOK AT IT. IT'S SO BIG. WOWEE. How will we move it?
>> We need to work together. Don't worry, friends. We'll figure it out. Wow, look at the size of that. I've never seen one so big. It's incredible. How did it get here? Let's figure it out together.
My tummy says it's time for a snack.
Our cave is perfect. No mud inside at all.
Is that for a for us? Of course. This is our victory feast. Yay! Mhm.
Ouch.
It's too hard. How do we open it?
It is very thick.
My claws are too small for this big fruit.
Don't worry, little squirrel. We'll help you.
>> [screaming] >> Do not worry. We have a new tool. We can use another lever to split it.
>> [laughter] >> And I found the perfect wedge.
This will help us start the cut.
All right. Perfect.
Amazing, Dodo.
It's centered. When I say go, hit the stone with the wood. Go!
Nice. Give it another one.
Ready, go. Go. Go.
You got this. Go.
Careful, Roro. GO. HOORAY.
NICE.
IT WORKED.
I see red.
I can smell the sweetness.
We need to find the right angle.
Let's try inserting it deeper. Yes, now we can pry it open.
Easy does it.
We don't want to squish it.
The watermelon's cracking. We have to help.
Let's analyze the fault line.
YAY.
YAY. [screaming] YAY.
I love this watermelon. Yay. And I love dancing.
Nice moves, Roro.
It looks delicious. It looks amazing.
I'm so glad we found it.
Here you go, Toby. This one is for you.
>> [snorts] >> Squeak.
This is the best thing I have ever tasted. It's so cold and sweet. Mhm.
Delicious. Best ever. So good.
Meow. A perfect reward for a perfect job.
Science is great, but science that gives you snacks is the best. That's true, Roro. The best indeed.
Mhm, this is the best watermelon ever.
I'm glad you both like it so much.
Indeed, it's quite juicy.
>> [laughter] >> This is what a successful day looks like.
Keep pushing. Almost there. It's moving.
We did it. Wow.
Thank you. Welcome home. Look, the cave is clear.
Wow, it's open.
We did it.
QUACK.
IT WORKED.
OKAY, safe on the moss. Now to the water. Squeak.
Our home. Home.
Yes, our home, Ollie.
Yay.
THE CAVE IS OPEN.
WOOHOO.
LOOK OUT.
HI, TOBY.
Look how much fun this is. We're so glad we could help. This is the best river ever. You found me.
Just like we promised.
Keep going, Roro.
Meow.
Now to the forest.
Science is amazing.
Soft meow.
Meow.
Brains over brawn.
Wait, I have a surprise.
Quack quack quack quack.
Quack quack quack.
Almost got it.
>> [groaning] >> Wow, it's huge.
He's rolling it. WATERMELON TIME.
PERFECT FOR A HOT DAY.
How do we open it?
It is very hard.
We use another lever.
>> [laughter] >> Quack. A mini lever.
Purr.
That's it, Kiki. Just like we planned.
>> [laughter] >> Found it. Now we can free Toby.
Almost there.
It's holding. Solid physics.
Now we pull.
Ready?
1 2 3 We did it. Yes. Now the others can be safe. Toby, Ollie, come on in. The fruit is open. It worked. It's safe now.
Look at that. It's perfect. Analyze the sugar content. Yum. Yummy.
Please help us get home.
We need a way out.
Can we have We're all here. We're reunited.
Let's do this. Okay. All right. Of course, friends.
Thank you, Dodo. You're very welcome.
Squeak.
So sweet.
>> [laughter] >> Oh, I wish I was home. Purr. This is delightful.
Meow.
Science helps friends.
Keep trying. We're almost there. This big rock is a challenge. Don't give up, Toby and Ollie. We can do it together.
Goodbye, Toby and Ollie.
Thank you for the help.
We did a great job today.
Meow.
We used our brains.
Quack, quack.
Amazing.
And we made new friends. Oh, who are they? They look a little sad.
Let's say hello.
