Zoboomafoo (1999)

S2E24 World of Legs

Zoboo catches sight of a larva and starts to ponder what kind of legs it will develop in the future. Will it have powerful legs like a tiger, numerous legs like a millipede, or the long legs of a kangaroo? When the larva eventually changes into a salamander, Zoboo is surprised to see that its legs are nothing like he had envisioned!
