The Carnivorous Plants are a plant that appeared in "Pitched Battle of the Tank Army".
The Carnivorous plants resemble large Venus fly trap plants. Most of them are green, but the main "flower" (where the treasure was hidden) is light pink with raspberry pink zig zags around its mouth. At one point, the main "flower" used 8 other plants as legs to move round. It was later turned into a pretty flower by the Demons.
