Eight, nine, ten!
Ready or not, here I come!
-Move over, will you? You're in the way.
-I was here first.
-Where are you?
-She's going to see us!
Crumpets! We're done for!
-Come out, come out, wherever you are...
Aha! Game suspended! We're live in five, four, three...
This is Brain Freeze!
With Dr Knowles...
..Colin, the floor manager...
..and Ms Hucklebuck.
Come on, everybody!
-It's time for...
Today we're asking...
In nature, animals and plants use camouflage to appear invisible.
Some animals use their colour and texture to blend in
with their environment, which can help when stalking prey.
Others have distinctive patterns
which act as visual disruptions to confuse predators.
And then there are animals
who use mimicry to make themselves invisible.
Mimicry? I love a good impression!
One such animal is the walking stick insect,
which looks just like a twig.
Amazing. That gives me an idea.
Ms Hucklebuck, I bet you can't find me!
See you after the break.
And we're clear!
Heh! This is the best hiding place ever.
I wonder where McCork could be.
She hasn't a hope of finding me in here!
I can see you, McCork!
Ha! As if! I'm completely invisible.
No, I really can see you, McCork.
You're standing right in front of me.
Ah, crumpets! Caught again!
Are you sure you don't want me to explain the rules again, McCork?
It's really quite simple.
Oh! Positions, everyone!
Argh! How do you do that, Dr Knowles?
So, Dr Knowles, which animal can turn invisible?
In the deep sea there are squid, cuttlefish and octopuses
who can change their shape, colour,
pattern and texture of their skin in an instant.
What? How do they do that?
Octopuses have special pigment cells in their skin
called chromophores. By controlling the size of these cells,
they can vary their colour
and even create changing patterns.
The mimic octopus goes even further
by changing colour
and moving its tentacles
to take on the appearance of other sea creatures.
There's no catching that fella!
So there you have it -
the octopus is widely considered to be the master of camouflage.
Which is also what they call me, funnily enough.
See you next time.
Agh! Who did that? Where am I?
I figured it out this time, lads, I know what I'm doing.
Ready or not, here I come!
I hope we haven't made it too easy for him.
Well, he is really, really bad at hide and seek, Ms Hucklebuck.
Anyone in here? Hello?
Ow! My head!
This is fun. It's really sore but it's fun.
Oh, dear. Do you think we should stop him?
No, let's let him tire himself out.
It's nearly time for his nap anyway.
Am I getting hotter or cold...? Ow!
OK, so I have my eyes open and you have to try and find me.
-No, you're it.
-It, what's it?
Oh, I am? Oh, now I understand.
