Someone please explain Ally's character to me

Why is Ally from Disventure Camp so drastically different a character, from her weird manner of speaking and bland personality in Season 2 debut, to her foul unpleasant disposition in Disventure Camp All-Stars?

I originally asked Ask AI as an experiment, but all I got were some vague answers, thinking that it collects data from various sites mentioning both her and the show.
