Croucars is a dark reddish-purple crow that replaces Twizzy in the Revenge of the King sub-game in Kirby Super Star Ultra, where Tookey, is also replaced by the pelican foe Cawcun. Croucars acts very similarly to Twizzy, he is just a bit faster, stronger, and has a bit more stamina. Some Croucars are also seen in the opening cutscene for Purple Plants, where they, along with some Koozers, fly at Kirby after he chases a solitary butterfly, pushing him away as they do so.
Croucars may also be related to the anime character Crowmon in Kirby: Right Back at Ya!.
