Again, in the same Lilo & Stitch scene, the musicians appearing in the background are playing for the dance class. Throughout the song, both of them are playing the same instrument as you can see from the screenshot above. However, later on, when Lilo tells them that “Pudge, the fish” controls the weather, there’s a shot that captures how they look at each other, fairly confused by that comment, while they hold their instruments. Right there you can see that magically one of the instruments has changed and is now a drum.
