The pokedexes are:
GRASLOTH, the Grass-type sloth Pokémon: it's a bit lazy, with its large arms it can hang from branches and perform maneuvers, and with its claws it can open berries.
Mosloth, the climbing Pokémon, Grass and Fighting type: this Pokémon is great at climbing, thanks to its long arms and claws that can penetrate rocks; they are very good at this skill, even so they don't climb much, since they are pretty laidback and generally rest under trees for about half weeks
Megalosloth, the giant Pokémon, Grass and Fighting type: they are the guardians of the forest, their great size brought about their downfall, as many hunters want to have their claws, they say these pokemon tell wisdom to careful trainers by their dreams
I'm not Mexican but i wanted to make an mexican region, the starters were gonna be based on popular animals from there
grasloth is just grass + sloth
mosloth is moss + sloth
and megalosloth is megalomania + sloth
(megalosloth being based on the gigant sloth, an pre-historic animal)
