Pop-up Gate

Pop-up Gates are objects in Mario vs. Donkey Kong: Minis March Again!. They are thin metallic objects that have a stop sign at the top, and extend from tiles with green upward arrows whenever the player taps them on the touchscreen. After activation, they stay up for five seconds before they retract back into the tile. They can be used to change the direction of minis.

Pop-up Gates can be first encountered in Room 2-SP, though they are properly introduced through a tutorial in Magnet Mania.
