P Panel

P Panels (also described as Orange P Switches, Orange Trample Switches, and Switch Panels ) are a rare variant of P Switch introduced in Super Mario 3D World. They are orange switches that, when groups of them are pressed simultaneously, cause a certain event to occur.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
In Super Mario 3D World and Super Mario 3D World + Bowser's Fury, P Panels appear mainly in subareas that reward Green Stars. The first set of P Panels appears in Double Cherry Pass after the first set of Blocksteppers, where they reveal the second Green Star. Two sets of P Panels then appear in Beep Block Skyway. The first one appears just before the split path with the first Green Star and reveals coins; the second one appears just before the Goal Pole and reveals the third Green Star. Two more sets of P Panels appear in Lava Rock Lair: one near the beginning of the level, and another within the level's Mystery Box; if fewer than two or three players are playing, (a) Brolder(s) must be thrown onto the remaining switch(es) to collect the first and second Green Stars, respectively. A single P Panel also appears in both Cakewalk Flip and Fort Fire Bros. in the areas where the second respective Green Stars can be found. Yet another set of P Panels appears in Rainbow Run in the area where the first Green Star can be found. The final set of P Panels appears in the third room of Mystery House Marathon; if fewer than three players are playing, Brolders must be thrown onto the remaining switches to collect the room's Green Star.

Captain Toad: Treasure Tracker
P Panels return in Captain Toad: Treasure Tracker, where a set appears in Double Cherry Palace; hitting both of them causes a wall to recede and allows the player to proceed through the level. The next set appears in Double Cherry Spires, and raises the smaller tower next to the Power Star when activated. Another set of P Panels appears in Poison Canal Cannon Run, where they are used to unveil the first Super Gem.
