Numbuh 5 and Heinrich Von Marzipan in “Unfinished Business”

Heinrich, what happened to you?! You've become a monster!

[sarcastically, as if flattered] Oh, you noticed. Well, it's all your fault! [sepia-tone flashback to the events of "Operation: R.A.B.B.I.T."] Because you showed up at the jungle's chocolate volcano and insisted on thwarting mein glorious plan to make chocolate bunnies from real bunnies, I fell into the choco-lava and fused with it. When I finally crawled out, I was forever changed. All the beautiful things became chocolate-y at my touch. It was like ein dream come true! [laughs maniacally] I actually thanked you for what happened to me! But many weeks later, I was taken over with a more powerful desire than I had ever encountered before—I desperately wanted to have ein cheeseburger! But when I went to take a bite—CHOCOLATE! It was the same with everything—french fries, soda pop, schnakenwurst, mayonnaise! [end of flashback] Everything became chocolate! [sobs] Oh, Abigail, I'm just ein hollow shell of ein boy.
