The Rugrats act out different animals. Tommy plays a wolf, but Dil thought he was a dog. After arguing over the issue with Tommy, Dil feels hurt and cries. Later, after the Rugrats' nap, Didi gives the Rugrats juice and cookies; the Rugrats eat theirs right away, but Tommy was still sleeping. Spike knocked the juice over, spilling on Tommy. Then, he shed some hair on Tommy. The Result -- Tommy thinks he's a monster, all because he hurt Dil's feelings. Meanwhile, Betty's brother, Freddie, pays a visit.
