Colossus was deceased hamster pet of Nassor.
When Nassor is convinced he can bring his dead hamster back to life, he attempts a reanimation experiment on his dead hamster, Colossus. When the experiment is complete, Colossus rose from the dead and came out of the tomb as a little wrapped rodentus monster.
At the Dutch Day Festival, Nassor summons Colossus to kill Shelley, but Colossus is squished seconds later by Shelley and died again instantly.
- Since the other monsters are meant to bare a resemblence to the original Universal Movie monsters, Colossus is meant to represent The Mummy. Ironically, Nassor, his owner, bares a strong resemblence to actor Boris Karloff, who not only played the Frankenstein monster from Frankenstein, but also Imhotep from The Mummy .
- In this movie, Mummy Hamster is voiced by Dee Bradley Baker.
- His death is based on the popular internet video Bambi Vs. Godzilla.
- Colossus's name is gag on his size.
- Colossus resembles Tim Burton's MummyBoy from the original poem.
