Research Notes - Poliwag
Hyla crocus

Most wild Poliwhirl don’t evolve, as neither Water Stones nor King’s Rocks are common items. Naturally, the Pokémon are neotenous, as they never mature into the standard morphology of typical anurans (for example, Greninja). Even upon evolution into Poliwrath, they still don’t quite resemble adult Pokémon from their order. This contrast is most apparent when Poliwag are compared with Tympole; while Poliwag and Tympole resemble each other, Poliwrath and Seismitoad seem far more disparate. Scientists think that Politoed represent what the Pokémon would look like if they weren’t neotenous, though the evolutionary advantage of neoteny is still a mystery.

Diet

Poliwag feed on the roots of lily pads and on algae. Poliwhirl and Poliwrath also consume plant material from time to time, but also catch insects and small fish as well. Politoed are exclusively insectivores.

Care

All members of the Poliwag family must keep their skin moist at all times, as they will suffocate if it dries out. Poliwag are clumsy on land and will stumble often. so trainers should keep a close eye on them out of the water. Poliwrath enjoy practicing their swimming technique, so trainers should take them out to large lakes often. Poliwag, Poliwhirl, and Poliwrath are entranced by the sound of Politoed croaking; trainers should recall their Pokémon if they hear the distinct sound.

Caution

Staring into the swirls on the bellies of any stage of this line other than Politoed can put a person in a trancelike-state. No members of this family are aggressive or dangerous to humans, making them excellent Pokémon for beginning trainers. Poliwrath, however, are very strong, and can strike with powerful punches when agitated.
