Fleeblebort is a small, green duck-like creature. He wears a blue hat and blue pants, and dresses elegant since he's going to a wedding.
He was going to the wedding between Marsha and Spats before Wander accidentally steals his carrot, making his hufflerumple stop. Things worsen when Wander mentions that carrots can get on stores, which causes the humfflerumples to leave Fleeblebort.
Wander and Sylvia help him get to the wedding, only to discover he was going to the wedding to stop it and exclaim his love for Marsha, which he does. The two, after Marsha cancels the wedding, then zip off into the distance.
