Koopa Kart series
The Blooper is an item featured in the Koopa Kart series starting from Koopa Kart DS. When used, it will squirt ink on all racers ahead of the user, similar to Mario Kart. Starting from Koopa Kart 7, it decreases the player's handling, making their vehicle hard to control. It can be obtained from 4th to 9th place in Koopa Kart DS, Koopa Kart 7, and Koopa Kart Tour and 5th to 12th place in Koopa Kart Wii and Koopa Kart 8.
