Lilo & Stitch: The Series (2003)

S1E18 Yaarp

One tranquil morning, Mrs. Hasagawa tends to her garden when she unwittingly activates Experiment #613, Yaarp, a creature that emits destructive sonic waves. Lilo and Stitch pursue the chaos, but when Yaarp unleashes its sound, Stitch suffers temporary deafness due to his enhanced hearing. Jumba notes that only someone without ears can withstand Yaarp, leading Pleakley to step up as an Experiment Hunter. After Pleakley manages to trap Yaarp, Stitch’s attempt to distract Gantu backfires, resulting in Stitch's capture. Gantu proposes a deal: Stitch in exchange for Yaarp, leaving Lilo in a tough position.
