Too Much Monkey Business - S5.E18

Danny's sister Wendy has returned to the USA from the African country of Uganda. Wendy is a primate researcher and she has a pet chimpanzee named Ginger, who quickly becomes attached to Jesse for some reason. Wendy is scheduled for a job interview at the local zoo, so Joey takes her to the interview. A package is in the mail, and when Stephanie and Michelle open it, it turns out to be a figure named "Nikata". The tag on it says that there will be a curse over the family if no one "feeds" Nikata.
