List of New Super Mario Bros. Wii glitches

This is a list of glitches that are found in New Super Mario Bros. Wii.

Infinite Coins
This glitch can be done anywhere but is more notably done in Wendy's Castle. When performed, it allows the player to gain an infinite ammount of Coins. At least 2 players are required to preform it, and at least one of them wearing an Ice Suit. When the player enters the Castle, they should go past the first spike pit and stop moving before the second spike pit. They should reach a Koopa Troopa on the Flip Gate (the right side right before the second Spike Pit), but must not attack the Koopa. The player with the Ice Flower should stand on top of the right ? Block (on the backside of the Gates), while the other should go onto the front side gate. When the Koopa is on the other side of the gate, they should both Freeze and hit the cage at the same time. If done right, the Ice Block will fall (with the Koopa moving around it) and 2 never-ending streams of Coins fly out (until the timer runs out). These coins can be interacted with, but the Ice block and the Koopa cannot.

The glitch can been seen Here.

If the coins are left alone for too long, the game will start to lag, but oddly, it won't crash. An example can be seen Here.
