Corrected entry: The first question of the Cinnabar GYM is "Does Caterpie evolves into Butterfree?". According to the GYM the answer is YES. However, Caterpie doesn't evolve into Butterfree. Caterpie evolves into Metapod and then Metapod evolves into Butterfree, later. So saying that Caterpie evolves directly into Butterfree is a mistake.

Correction: It doesn't actually say directly though. Caterpie does eventually evolve into Butterfree.
