The Adventures of Peter and Wolf
The Case of Trihead the Dragon
S1 E3:
The three heads of the dragon have gotten into an argument yet again: the middle head is now focused on self-improvement and is encouraging Trihead to play music. The other two heads can't stand it and kidnap Wolf so he'll introduce Trihead to Peter and put a stop to the racket. Wolf asks Peter for help, and Peter comes up with a good fix.
