Place this clip at the reveal of the belly-up pose, then follow the reaction with a cat laugh meme for the family response, or a baby laughing meme if the pet owner gives in and starts washing.
About this sound
The clip is a short voice line where a character introduces himself as Pibble and asks to have his belly washed, delivered in a sweet, pleading tone over about three seconds. It feels cute and silly, like a spoiled pet demanding attention, and that earnest begging makes the request sound funnier than a normal dog moment.
