Movable Pipe

Movable Pipes, also generically referred to as Green Pipes, are a variation of Warp Pipes that first appear in Mario vs. Donkey Kong: Mini-Land Mayhem! They appear as transparent Warp Pipes with dotted line outlines, but when the player uses their stylus to tap them, they turn into fully functional Warp Pipes. The player has only two such Warp Pipes at their disposal, regardless of the number of pipe outlines in a level. Entering into an already existing Warp Pipe leads to the other non-outlined Movable Pipe, or vice versa. A Movable Pipe that is not connected to another end will simply lead the Mini in the opposite direction. They are first seen in Area 4-1 of Warped Mansion and appear as a common mechanic of that attraction. Movable Pipes only appear in the color green to distinguish them from other Warp Pipes.

Movable Pipes also appear in Mario vs. Donkey Kong: Tipping Stars where they are introduced in Level 4-1 of Crumbling Cavern, and Mini Mario & Friends: amiibo Challenge where they are first encountered in Level 10. They behave the same way as they did in Mini-Land Mayhem. However, in Mini Mario & Friends: amiibo Challenge, their outlined form appears to be a much greyer color.
