Okay, soon I'll make some english names that could fit in to compare the japanese names, okay?

Here they are:

Tsutarja ---> Snapivy
Pokabu ---> Pyroink
Mijumaru ---> Ottwater

Snapivy's name come from "snake", the "snap" sound which a snake can bite, and "ivy"

Pyroink's name comes from the Greek word "pyro" which means "fire", and "oink" which pigs make a sound.

Ottwater's name comes from the combination of "otter" & "water", which has the similar rhyme.

Those english names I made are not real, they all just 100% fan-made! Soon on November 22nd, the real names will be revealed in the pokemon website!
