Bim-Wim-Lim-Dim-Ponko was a creature which was originally five individual carnivorous dinosaurs. The five friends became volunteer test subjects for the daspletosaurus scientist Professor Hydra, who used his MAMMA machine to merge them into one five-headed and five-tailed dinosaur, promising to change them back to normal once his plan was finished. The creature seemed to be less independent than the halves of Rojan-Jack, although it was aware that it was made up of multiple individuals. It lived in an old servants' village on Doctor Frankensaur's asteroid.
