Seems like it really took a long time before bunny nun finally lost that habit of hypnotizing victims into bunniness

Someone tell Hook-Bang she's supposed to eat the WHOLE carrot.

Bunny Nun: "Good... Now say "What's Up Doc" and later I teach you the way of the "Big Chungus" in detail."

Bunny Nun wanted a successor? She still has to learn to treat humans well and not force hypnosis onto them.
I give her the benefit of the doubt that the Bunny Bunch Ducks follow her out of their own free will and just imitate her scary expression.
