Shortly after Ben and Flo bring Junior home, Big Ben visits them and is shocked that they adopted. Junior's bedroom catches fire when he shorts out the clown lights, and Big Ben calls him "The Devil". Junior throws Flo's cat at Big Ben and they both fall down the stairs and are injured. Next, Junior ruins a camping trip with the neighbors by urinating on the campfire and luring in a bear to scare Roy's kids. He then sabotages Lucy Henderson's 6th birthday party, after she snobbily bans him from her magic show for touching her presents. Ben gives Junior his lucky prune, which his grandfather gave him shortly before he died, and which he considered a special bond. Finally, Junior wins a Little League game by belting rival players with a bat for bullying him. Horrified, Ben decides to return Junior; however, after hearing from Mr. Peabody that Junior was returned 30 times, Ben decides to love him, which no one else has ever done before. However, Ben absent-mindedly leaves his keys in the car, and Junior drives through Big Ben's sporting goods store, leading to Ben's individual retirement account being seized to pay for damages.
