The Stairway to Heaven: After going through an easily discoverable secret door, the party finds a spiral staircase. Going up (or down) takes a while, but leads to a door. Going through the door, they find... another spiral staircase. Which ends in a door leading too... another spiral staircase. Naturally it is all the same staircase with a dimension door between the top and bottom doors. To get out, they must find that original secret door... which is much harder to find this time.

Smells like Teen Spirit: The room is locked and full of the wandering ghosts of teenagers. To escape, the party must resolve all of the teenager's various teenage dramas... love triangles, missing math homework, who's dating whom, and of course, where can they find a fake id to get some ghostly booze.

Free Falling: The floor opens up and the party begins to fall into a bottomless pit. Actually, it's an illusion and they have all had levitate cast on them, but it might scare them for a bit.

Just Another Brick in the wall: Endless tide of monsters through a narrow corridor, loads of bricks lying around. Wasn't that the way we came through, though?

These Boots are Made for Walking: River of lava. One pair of fire-proof boots. How to get everyone across?

And of course, the dance fight finale. Characters singing and dancing while fighting receive substantial bonuses to attack and defense.
