They have since become a nuisance as they have been getting into multiple testing facilities, the walls and have been found as deep as the deep storage room. They have also been chewing through wires and attacking Simon at random times. In the episode of "Soul Absorber" on Yoglabs, Simon kills one of the Hammy Hammstas to morph into it. This was to sneak into the walls under the floor and into the party room, as the hamster was small enough to do this. Simon then killed Fry Cook Shelby to morph into him.
