'''Crumbling Cavern''' is the fourth world of ''[[Mario vs. Donkey Kong: Tipping Stars]]''. It occurs inside a vast and heavily-rugged underground zone, littered with boulders and other mineral formations. Several pipes are spread between the rocks, and sewage flowing from a grated drain can be seen in the far background, sometimes obscured by foreground elements. The gloomy, indigo-hued environment, along with its cave and sewer themes, are reminiscent of the underground levels of most ''[[Super Mario (series)|Super Mario]]'' games. This is aided by the soundtrack that plays in most of its levels, which is an arrangement of the Underground theme from ''[[Super Mario Bros.]]''.

As with other worlds in the game, Crumbling Cavern introduces a new mechanic, which is a pair of [[Movable Pipe]]s that can be picked up and repositioned in preset locations to suit the needs. 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 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 (toy)|Shy Guy]].
