Danny's younger sister Wendy has returned to the U.S. from the African nation 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. At the same time, 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. It turns out that the Nikata is an African piggy bank that Wendy ordered as a souvenir, so the only "food" he needs to be "fed" is, what else? Money. Apparently, they used real food to lure Nikata, not knowing that money is his "food" in the first place.
Joey and Wendy did not get along with each other when they were kids, but now, by the time Joey and Wendy get home from the zoo, they are getting along great. Danny notices that, and he tells Joey not to date Wendy. Joey thinks that Danny is being an overprotective brother to Wendy, and Danny starts following Joey around the house to try to explain things. As it turns out, Danny does not want Joey to date Wendy because she is the kind of person who is so committed to her job that she could pick up and end up halfway around the world at any time, and Danny has seen Wendy hurt a lot of guys in that way. Wendy obviously does not intend to hurt Joey, because she has decided to take the job at the zoo.
