When Mrs. Sparklenose takes the class on a field trip to Colonial Trolliamsberg, the students see Garfunkel the Griffin performing the center of town. However, Niblet's flash-photography causes Garfunkel to freak out and angrily fly to the sky and the only way to get him down is to whisper "Nap time" in his ear. Abby tries, but the person must be a troll. Blogg flies up to put Garfunkel to sleep.
His name and hairdo are a reference to Art Garfunkel, of Simon and Garfunkel.
