Not so much 'impossible' as 'routine'

Squirrels really work for their food.



Although, really, it's mostly just climbing things and walking across other things. Squirrels do that all the time. The only remotely interesting parts are when it leaps from part of the obstacle course to another (which probably isn't far outside what squirrels do in trees anyways); the fact that it seems to be dragging the little red cart forward by pushing along the sides of the tube (again, not that amazing); and the initial jump, where it "lands" on a windmill blade. But that's just amusing.

When they start solving complex puzzles that open the way to the next obstacle, then I'll be impressed.
