Stitch and Lilo in “Holio (Experiment 606)”

[Stitch goes into the pet shop, alone, disguised as a bunny, to see the number on the experiment pod on Mertle's bracelet as she and her friends enter while Lilo hides in the backseat of a police car to try and stay out of trouble]

Stitch

[through walkie-talkie] Experiment 606.

Lilo

[opens up Jumba's computer and searches up Experiment 606; horrified] Oh, no. [on walkie-talkie] Stitch. Come in, Stitch! Experiment 606 is a black hole that will suck in the whole world!
