Beavowl has to be my favorite while he isn't used that much the concept of two villains sharing one body is one of the reasons why I like him and Venom aside from him my others include Eyesaur and Grunkfuss cuz I love hiw they are outta place in an outta place series Grunkfuss's heavy creepiness and Eyesaur's morbid origin and Flumpty himself for how he slowly loosses his cool if he ever had sny
My theory The beaver might run too fast to the toilet and make them trip And Fumpty thought he was poop And the owl hit the vent to hard and which means his speed and his mouth open and choked on the urinal and Fumpty combine them too into the beavowl
