Carnivorous Flowers (as their name indicates) are giant beautiful red flowers who, despite appearances will eat anything that comes their way. The only thing they don't eat are other flowers, as such they won't eat anything that looks like a flower. Yakemeleons take advantage of their flower-like tongues to avoid these vicious flowers.
In the Movie
Ugga, Sandy and Gran encountered some of these flowers and to avoid them they wore giant flowers over their bodies to disguise themselves after seeing a Yakemeleon avoid them with its "flower" tongue.
