The Vamporilla is a cross-between a vampire bat and a gorilla that appears in the fourth Give Yourself Goosebumps book, The Deadly Experiments of Dr. Eeek.

It lives inside a padded room opposite the waiting room at a laboratory, and it is violent enough to kill any intruders. It is never revealed how this creature came into existence, but is most likely one of Dr. Eeek's experiments, as other hybrids (such as dog/humans) have been created by him.


  • Although it is depicted as a chimpanzee on the cover, the Vamporilla is supposed to be a gorilla.
  • Despite being on the cover of the story, the Vamporilla is only present in its one bad ending where you and Sam run into it in the labs and are quickly destroyed by it.
