Bud

Bud is Lab's ace Floragato, he's usually very chill and loyal yet a slight bit anxious

Bud will appear in every episode of LATM so he is more of a secondary character, though like the other Pokemon he won't have full dialogue, rather he just repeats his name in a tone so that the audience can tell how he feels, there is dialogue in the audition but that's more so just to see your potential range

Voice wise he should sound the same as Puss in Boots from the Shrek franchise
