A 20th level sorcerer who was polymorphed into a toad by a Hag who affected him with a Bestow Curse and a Geas that forces him to sing about every actions he undertakes.
Or the other way around, a toad polymorphed into a 20th-level sorcerer. Just walk around absentmindedly chasing flies until danger approaches. Then say “ribbit” and roll on the Wild Surge table.
(although I do love the reference)
