Humphrey

Humphrey was an ex-detective with his partner Bogart. When there are countless pranks all over Angel Grove, they appeared at the Youth Center and volunteered to solve the case. However, Katherine Hillard and Tanya Sloan found out that they themselves were the pranksters and were plotting to put Bulk and Skull out of the detective business. As they were about to pin the blame on new student Robert, Kat and Tanya got them exposed by bringing the owner of the novelty shop that they bought from for their pranks. After they were caught, Kat and Tanya forced them to apologize to Robert and they were escorted out of the Youth Center to face an unknown punishment for their crimes.
