He adores flowers and their smell, like Daisy. He doesn't have much courage, like Toad.
Unlike other Bunties, he has a special sense of smell. He can smell something that humans usually can't smell, even from far away.
Bunty, and the Bunty species, debuted in Super Mario Star Journey. Unlike most Bunties, he resides near Patchy Flower Patches. In the first mission, Mario has to follow him, as he smelled a Power Star from far away. However, he can't move with an enemy in the way, so Mario has to make his path clear by defeating enemies while following him.
