All 4 players must be Link. At hyrule castle (or any place with a straight wall) all four links should walk to the right, fall into the place with the canopy, and run left against the wall so they are inside each other. Then let the game push them all apart. After this, all 4 links must simultaneously throw bombs upwards weakly, quickly. After just a few throws, the bombs will hit each other and continuously stay, trapping the players within.
This glitch involves the usage of Training Mode's ability to spawn items. By creating 4 Green or Red Shells in the same location, attacking them with various moves will deal ridiculous damage to the attacker, the opponent, or possibly both. Multiple variants of this glitch exist.
Mario Tornado
Possibly the most well-known version of the glitch, caused by using the Mario Tornado to simultaneously hit an opponent and a stack of Green Shells. As the shells and the attack hit each other and the opponent in a chain reaction, all of them will be locked in freeze frames until the items eventually vanish and the Tornado can run to completion; the time this takes (about 30 seconds) is guaranteed to ring up the opponent's damage to 999%. As the Mario Tornado has fixed knockback, the opponent will not be KO'd once the glitch completes, though essentially any other move will. This can also be done with the Super Jump Punch, Luigi Cyclone, and Screw Attack. Using Red Shells instead of Green ones will cause more unpredictable results, such as immediately raising both characters' damage to over 800% and knocking them both away with fixed knockback.
Ground Pound
This variant involves Yoshi using his Ground Pound into a stack of Red Shells near the opponent. If done correctly, Yoshi and then the opponent will each receive about 250% to 400% damage.
Spin Attack
This variant involves Link using his Spin Attack on an opponent and a nearby stack of Red Shells. If done correctly, the opponent gains up to 999% damage and slashing sound effects can be heard.
Ness's forward smash
This variant involves using Ness's forward smash (his bat) on a stack of a stack of Red Shells next to the opponent. If done correctly, the opponent will take 600% to 999% damage and go flying. This may also hit the player, depending on the distance from the shells.
The result of Mario rolling to the right in the left picture and the result of Mario doing the opposite in the right picture.
The player has to use Mario for this glitch. Mario must go to any stage with a wall and stand against a wall. Then he must use shield and roll against that wall as much as he can. If Mario is rolling left, he goes further away. If he is rolling right he goes towards the camera. If Mario falls or gets attacked, he reverts to normal.
Only 2 players are required for this glitch. One should be Ness, the other should be Fox. Choose a stage with a direct line between Ness and Fox (ideally, Hyrule Castle or Sector Z). PK thunder against Fox's reflector so that the PK thunder is in direct line back to Ness, and quickly bat the PK thunder away. The thunder should have 2 tails, and if it reaches the edge of the screen, the game can't handle it and will freeze.
