Turtwig actually exists, and it can be found in real encyclopedias. You may read more about it on the following wiki(s):

Turtwig is a grass-type Pokémon species. Turtwig mostly resemble turtles with their dark brown shells and face, however, they sport a leaf sprout on the top their heads. They are not a very violent Pokémon species, as most are very shy and lazy. But some are very outgoing and protective of the ones it loves. It evolves into Grotle starting at level 18, who evolves into Torterra starting at level 32. Along with Piplup and Chimchar, Turtwig is one of the other starters of the Generation IV games, Pokémon Diamond and Pearl.
