'''Crumbling Cavern''' is the fourth world of ''[[Mario vs. Donkey Kong: Tipping Stars]]''. It introduces [[Movable Pipe]]s, a pair of green [[Warp Pipe]]s that can be picked up and repositioned in different areas. Once a Mini toy enters one of these pipes, it will be warped out of the other one in a different area. All other mechanics that debuted in previous worlds make a return in this world, though without as much focus put on them. The only enemy species introduced in Crumbling Cavern, [[Fire Piranha Plant]]s, are able to spit fireballs that bounce off the opposing surface and return to the sender, repeating the attack. Other enemies found in this world are [[Cannon Kong]]s and a single [[Shy Guy]].

The background of Crumbling Cavern is a rugged underground zone with boulders and other mineral formations. Several pipes are spread between the rocks, and sewage flowing from a grated drain can be seen far in the background. The blue or indigo-hued environment of this area is reminiscent of the underground levels of most ''[[Super Mario (series)|Super Mario]]'' games. The soundtrack that plays in Crumbling Cavern's levels is made of variations of the [[Underground Theme]] from ''[[Super Mario Bros.]]'', which was also the basis for the themes of [[Magnet Mania]] from ''[[Mario vs. Donkey Kong 2: March of the Minis]]'' and ''[[Mario vs. Donkey Kong: Minis March Again!]]'', as well as [[Secret Storage]] from ''[[Mario vs. Donkey Kong: Mini-Land Mayhem!]]''

There are two [[Bonus Levels]] that are set in this world, [[Level B-7|B-7]] and [[Level B-8|B-8]].
