If they were part plant, then they wouldn't have a craving for O'Berries, since they could just make their own food every now and then.

Mex, you can't combine animals and plants, that's why both classes are separated by kingdoms. It would be a total oxymoron. Pollination is meant for organisms that don't move (like plants) because it's the only way aforementioned organisms can spread gametes. Puffles can move, so they don't need to spread pollen everywhere.
