Duck, Professor Zane and others in “Unfinished Business”

Sounds like someone's mommy didn't give them enough chockies when they were wittle!

[entertained but also disgruntled] Oh, you're just as naive as the Acmetropolis Science Council. Imagine, firing me because they deemed my experiments too "dangerous". They never appreciated me, all my genius, my...

[interrupts] Insanity, craziness? Am I getting close?

[unfazed] Hardly. I decided Acmetropolis needed to see first hand what I am capable of. [His flashback to the meteor hitting Acmetropolis is shown as he begins to tell his story.] When the meteor hit Earth, the impact opened all kinds of fissures.

[continues his story as the Fuz-Z's appear in the flashback.] I discovered these delightful creatures. [His flashback self picks up a Fuz-Z.] Their biology was perfect for the experiments I had in mind: experiments that led to the Fuz-Z. [He feeds a Fuz-Z some chocolate in his lab in the flashback, which mutates it. He activates a pulse from his electric leash to put the Mutated Fuz-Z under his control. The flashback ends as he finishes his story.] So cute and cuddly, until they have a bit of chocolate. Then, the only way to stop them is with this.

Care to demonstrate?

No. They need their protein.

See? Too much chocolate will make ya sick.
