Underwhere Road

Underwhere Road is the setting of Chapter 7-2 in Super Paper Mario. It connects the Underwhere and the Overthere to one another. It is almost impossible to see in Underwhere Road, but Tippi's ability doubles as a flashlight to see where you're going. Mario and Luigi are guiding Luvbi back to the Overthere in this level.

At one point in Underwhere Road, there are three D-Men holding a door closed. They claim that they are trying to hold a monster in, and they're sure it's definitely the same monster that has escaped the Underwhere. Mario and Luigi offer to defeat the monster for them, and, though skeptical, they allow them in, saying that if they aren't killed, they'll allow them to pass.

As it turns out, it is not the monster they were thinking of, but rather, Bowser, complaining about the situation he is in and how hungry he is. When Bowser asks where Peach is, he is told that she isn't there; however, he misunderstands them, believing that now that Peach wasn't there, they were going to attack him. After a fight, Tippi explains to Bowser what is going on, and the Koopa King rejoins the party.

There are three sealed doors that they must pass through, and only by passing the tests can they do so. Dorguy the First has questions that at first seem complicated, but then are revealed to be ridiculously simple, as the question itself is often unrelated to the story preceding it. Dorguy the Second has a more difficult quiz, based on memorizing the colors and patterns of moving shapes shown, and only announcing how many were right at the end. At one point, he stops announcing questions by numbers, challenging the party if they know the number of the question by the top of their heads. Dorguy the Third has a drastically different test; he summons the Underchomp, and the party must face it in a turn-based battle reminiscent of old RPGs such as Dragon Quest, or a lot like is predecessors like in Super Mario RPG, Mario & Luigi: Superstar Saga, Paper Mario, etc.
