OK K.O.! Let's Be Heroes Carl

Carl from OK K.O.! Let's Be Heroes cartoon is an invention developed by Professor Venomous. The episode where he appeared has the same title as his name. Also, Carl can't speak, so he can only say one line - it's his name. He is a green slime, the same substance found in "The K.O. Trap". He has a round body, a circular head, eyes, and a mouth, but he even doesn't have legs. Even though he is small at first, he can grow to be quite large. Carl was harmless when he was a little substance. When he grows up he becomes angry and baleful, and when he gets angry the most, his body turns into fire. A fanart OK K.O.! Let's Be Heroes cursor pack with Carl as cursor and pointer.
