as for petunia, she was originally meant to be a sweet smelling skunk, but the creators allowed flanderization to slip through and gave her OCD.

Flanderization means a trait in a fictional character being exaggerated. She's not the only character, here are examples below:

Splendid (uncaring nature towards job)

Pop (he's become a much worse parent)

Flaky ( she has more phobias than ever)

Giggles ( from the chick or damsel in distress to a granola girl)

Lumpy (his  many occupations)

Cro Marmot ( able to do average things offscreen, now extremely talented.)

Disco Bear (his poor lifestyle)

Nutty (his sugar addiction got so bad he's falling IN LOVE with candy)

Sniffles (he has been inventing loads recently)

Flippy (his character hasn't changed, it's the episodes he's in)
