Gobo finds out about Uncle Matt's Secret Rules for Exploring through a postcard, and decides to open up a school for explorers. On his first expedition, he- along with Red, Wembley and Mokey- must travel to the Hole To Who-Knows-Where. Gobo becomes so fixated on the rules that he starts to disregard common sense, and of course, he and Red go at it again. Wembley and Mokey start to agree with Gobo's rules, but before long, they both side with Red. Gobo decides to go find the Hole To Who-Knows-Where by himself, not knowing that he is still tied on to Red. When Gobo and Red fall through the Hole, Gobo needs to use logic to get back home.
