Yes. The pokemon franchise run out of names (at least by now I bet!) so they make some random name that well... isnt that "creative" and then other names are WOA....Could be both "squirt" and "squirrel". The Pokemon franchise is well known to be full of incredibly punny names.
That's highly unlikely. "Squirt" makes sense and fits in with "Blast" in Blastoise's name. Squirtle does have a tail, but it isn't a bushy one like that of a real life squirrel, so it isn't a sure thing that this was inspired by a squirrel. "Squir" COULD be both "squirt" and "squirrel" but the games, series and no other translations of the Pokemon's name even mention a squirrel at all, nor does Squirtle show any Squirrel like characteristics (e.g. living in trees).Squir is probably from squirrel and not squirt. The clue is Squirtle's tail. If it wasn't its tail, we would say that it is Squirt.
