Stu Pickles, Tommy's dad, creates the PlayPalace 3000, which is a huge playground made out of many zones that expands out of a small metal cylinder. As Stu is heading out to buy more supplies, he leaves Lou to watch the kids for him. When he falls asleep, Angelica enters the PlayPalace 3000 and steals the toys (Tommy's Lion (presumably Henry), Superthing, Wawa, and a bag of worms). She challenges the Rugrats to come and take them back.
