Sally Monster

The monsters are used as part of a game invented by Grover called "Where Did the Tallest Monster Go?" Bill is tall, Phil is taller and Sally is tallest. They also have different colored hats - Bill's is red, Phil's is blue and Sally's is yellow. The monsters then dip below the frame, with only their hats visible. Each monster pops up, startling Grover until he passes out. The puppets are modified versions of the AM Monsters previously used as Pearl, Narf and Kermit the Forg, respectively.
