Slurpstack

Slurpstack was a monster which appeared in the episode Something I Ate in Cartoon Network's animated show Ben 10.

Description
A large, purple beast with a row of red spines running down its back, Slurpstack had ten legs, the rearmost pair being used for locomotion with the remainder switching between use as arms and legs. Although a powerful opponent, Slurpstack was not really an evil creature, as seen when it befriended Gwen when the girl tried to help it get over its tummyache.

History
Slurpstack was created by mad scientist Dr. Animo to be used in his plot to rob Fort Knox. However, Team Tennyson happened to be on a tour of the fort at the time, and after Slurpstack got a sore stomach from eating all of the gold bars, Ben was able to knock the creature out using his knowledge of biology possessed by his Grey Matter configuration.
