Uncle Matt's coming back home again, and this time when he shows up, he hides under the party table in Gobo's room to avoid what he calls "Face Erasers." Red pokes fun at Matt's cowardice, even when he says it was a joke. Gobo gets upset that Matt won't admit his fear, so Matt goes exploring by himself. When Wembley convinces Gobo to go after him, they find a scary wooden statue of a Fraggle. When Matt accidentally hits it, they both fall through the floor and happen upon a whole new cavern with dozens of tunnels. And when you hit the arch to the tunnel, you get sucked into another region of "Outer Space", thus providing new places for Gobo and Uncle Matt to explore.
