But he'’’s way ahead by now.

We'’’ll never catch him on foot.

Martin might be able to stall him.

I mean, we can'’’t just stand here.

Aww.

Thanks, Stuffo.

But I'’’m not really hungry right now.

Aww, Stuffo, we really need to figure something out here, okay?

Stuffo, no!

That doesn'’’t go in there.

Wait, a bamboo clue!

I think he might be trying to tell us something.

Half eaten bamboo, the Buzz Bike, is this some kind of ancient panda secret?

Can we somehow get our Buzz Bike going with bamboo?

Well, pandas do get their energy from bamboo.

Hey, the scan we took of the panda'’’s belly!

Maybe that'’’s where the secret lies.

But there'’’s only enough power to turn it on once.

We'’’ve got to do it.

We'’’ve got to trust Stuffo.

AVIVA: Who wouldn'’’t trust a face like that?

Okay, here goes.

There'’’s the stomach and intestine.

Zoom in on it, even more!

Microbes!

Microbes!

Tiny, little, microscopic creatures that digest super tough plant material and convert it to energy!

Lots of plant-eating animals have microbes in their digestive system right?

Yeah, but a panda'’’s digestive microbes are different.

They'’’ve got to be super fast-acting, because pandas'’’ digestive systems are so short.

So, they have a special, super ability to get energy from plants.

Microbe power!

Aww.

That'’’s what you were trying to tell us.

Aww, thanks, buddy.

If panda microbes can turn plants into energy, they just might be able to power us back up.
