Season 1 focuses more on the plants' school life, Season 2 is more of an out-of-school season. And Season 3 is very fantasy-like.

It all makes sense, Season 3 contains episodes with mystery potions, legendary stuff, golden rare plant food, rare event that occurs every 100 years, magic, a flying mask named Agamenon, a time machine, body-switching, and a video game that sucks you into it. These things don't exist in real life.
