In order they are suganook (pronounced like sugar), candit, and caneiving. They start pure grass but become grass/dark and candit.
Here are some Pokedex entries for them
"Suganook start their life looking for a suitable stalk of sugar cane that they keep with them for life. If it brakes, they can regrow It from any remaining pieces but it takes quite some time to fully fix it."
"Candit are natural gatherers and will spend most of their day scooping up berries and stashing them in their tail. They have even been known to steal from other pokemon, though they are pretty charitable towards individuals they consider friends."
"Caneiving are rumored to be some of the greatest thieves in the region, although it's not 100% certain due to them never being caught. All everyone can use as evidence is the green blurs and woody tapping they hear right before a possession of theirs is take, that and the fact they have been seen with the occasional human made item in their tails."
Caneiving would have a grass type signature move called "bushwhack" an 80 power physical move that ignores moves like detect and protect, ignores terrains, and doesn't come in contact with the pokemon. It has pickpocket as it's ability.
