Squirtizan's are a recent discovery and because of that their origins are unknown. It is theorized that they are a distant cousin of Ickthyperambuloids, but there is little to no evidence supporting that theory. What is known however, is that the species is easygoing and doesn't get into conflict.
- Backwash is based off Mudkip from Pokémon.
