Lilo & Stitch: The Series, Season 2

[Lilo and Stitch have discovered an experiment that cleans up pollution and name it Ploot; Stitch catches an illness that makes him turn yellow, sneeze and grow extra arms from eating too much garbage]

Jumba:
Hard to believe I can't solve problem. I'm evil genius.

Lilo:
You sure are a genius. You invented Ploot and he's not even evil at all.

Jumba:
What is experiment you call Ploot?

Lilo:
The one who cleans up the pollution.

Jumba:
Cleans pollution? Hmmm.... Ah! You mean Experiment 515! [chuckles] No, no. Is not cleaning pollution. Is collecting pollution.

Lilo:
What's the difference?

Jumba:
The more pollution he collects, the larger and bigger he grows, until he becomes large pollution beast! Then he creates a thick black sludge, which he will spray all over town until everything is covered in a stinky coating of its own trash! [laughs maniacally]

Lilo:
That's pretty evil.

Jumba:
Thank you. But 626 is most unwell. If you wish to protect island from being smothered by its own pollution, you'll have to go alone.
