Fake Item Box

The Fake Item Box is an item found in the Mario Kart series. They resemble regular Item Boxes, but they do not bestow items to karts that pass through them - instead, the item acts as a hazard that flips vehicles over. Fake Item Boxes are generally obtained by racers near the front of the race, being used as traps similarly to Bananas; however, after Mario Kart 64, Fake Item Boxes cannot block incoming shells.

Mario Kart 64
The Fake Item Box's first appearance is in Mario Kart 64. They appear identical to regular Item Boxes with a key difference: the question mark inside is upside-down (a ¿ instead of a ?). Karts that collide with one are blasted into the air. Like Bananas, they can be used to block incoming shells, though unlike Bananas, they cannot be tossed forward.

If placed midair, the Fake Item Box floats; this is the only game where Fake Item Boxes are unaffected by gravity.

Mario Kart: Double Dash!!
While Fake Item Boxes are absent in Mario Kart: Super Circuit, Fake Item Boxes (called simply Fake Items in the Nintendo Power guide ) appear in Mario Kart: Double Dash!!. Here, they have a ¿ symbol and are also colored red. However, the color cannot be seen from a distance - only when approaching will they turn red. They can be destroyed by running into them with a Super Star or picked up with Hearts, as other obstacles pass through them, including all shells, eggs, Fireballs, and Chain Chomps.

Mario Kart DS
The Fake Item Box's next appearance is in Mario Kart DS. They have a new set of differences from a real Item Box: they lack a "?" entirely, they do not spin around, and they show up as red on the bottom screen's map. Their overall behavior is much the same as the previous game, though they do not bounce when thrown. Additionally, they get knocked away if a racer collides with them instead of exploding as all other iterations do.

Missions 4-6 and 7-8 involve collecting a number of Item Boxes while avoiding Fake Item Boxes.

Mario Kart Arcade GP 2
Fake Item Boxes appear in Mario Kart Arcade GP 2. They resemble regular item boxes, except they have a ¿ symbol rather than a ? symbol. This makes them similar to their appearance in Mario Kart 64.

Mario Kart Wii
The Fake Item Boxes return to their Mario Kart: Double Dash!! look in Mario Kart Wii, with a style change to match the new style of the real ones, as well as being larger than in the previous games. While they still have a ¿ sign inside, like in Double Dash!!, they can hide their red color at a distance - only on approaching do they turn red. Fake Item Boxes become blue instead if they belong to the blue team in team play. Much like in Mario Kart: Double Dash!!, Fake Item Boxes can be destroyed only by colliding into them.

Trading Card Info
Description: "Deception. That's what the Fake Item Box is all about. It looks remarkably like a real Item Box except that the question mark inside of it is upside down. Many a racer has found out the hard way about the treachery of the Fake Item Box and those who drop them. But like the saying goes, it's always better to give than to receive. Words to live by when playing Mario Kart Wii, for sure."

Game Tip!: "Carefully drop a Fake Item Box within a cluster of other Item Boxes or directly behind a real Item Box so your rivals will run into it and crash."

Mario Kart Arcade GP DX
Despite their absence in Mario Kart 7 and Mario Kart 8, Fake Item Boxes make a reappearance in Mario Kart Arcade GP DX, serving the same purpose.

Trivia

 * In Mario Kart Wii, if the player selects a team race or battle mode first and chooses the blue team, then exits and plays Grand Prix or solo Vs. mode, the Fake Item Boxes will be blue instead of red.
 * A Fake Item Box was going to appear in Mario Kart: Super Circuit, but was taken out for unknown reasons.
 * The instruction booklets for Mario Kart: Double Dash!! and Mario Kart DS erroneously state that the Fake Item Box can be used to block incoming shells, when they cannot in games following Mario Kart 64.
