The Fist Thingy is the first official way that contestants are eliminated on Inanimate Insanity at "Elimination Time!". It is a red boxing glove with the label "Fist Thingy" on it attached to a gray or white pole that shoots out and punches the contestant that receives the most votes either from the contestants or viewers at full speed in the Elimination Area. It sends these contestants flying off the show to Idiotic Island, where the contestants shall remain. The gray/white pole can shoot out straight forward or diagonally. The Fist Thingy was at one point retired from its original job and instead used to keep intruders out of Idiotic Island, but was brought back soon after.
The Fist Thingy makes its first appearance in The Arena Of Death when Pencil, a character from Battle for Dream Island, appears after being offended by Nickel saying that pencils were stupid. MePhone4 is annoyed that Pencil interrupted the elimination, and hits her with the Fist Thingy. This also helps show what the Fist Thingy is to the contestants, and MePhone4 goes on to explaining what it is.
After its debut, the Fist Thingy continues to operate until The Snowdown, where the elimination area is changed, no longer needing the Fist Thingy in order to eliminate contestants. However, it is used a few times after its temporary retirement to punch Pepper's Salt doll, and keep Bow out of Idiotic Island. It is used several times in the next episode, continuing its job to keep Bow off the show, punching her inside Idiotic Island, at the elimination area, and even in the Cacti Desert, being the main reason why Bow actually won the contest. It returned as the way people were eliminated starting with Crappy Anniversary. MePhone4 has also used the Fist Thingy in The Great Escape to quiet Paper down during the contest, and send MePhone4S away in The Tile Divide.
Even though the fist thingy was replaced in Season 2 with the portal, it reappears in Everything's A-OJ, sending the previously eliminated contestants back through the Rejection Portal. It also reappeared in Inanimate Insanity Invitational to send the eliminated contestants to Indefinite Island as the Fist Thingy III.
