Bigmin is a glitch in Super Smash Bros. Ultimate involving Olimar's Pikmin and Mother Brain. To perform the glitch, Mother Brain needs to be summoned from an Assist Trophy by Olimar's opponent. When Mother Brain is growing Olimar needs to use Pikmin Throw on the expanding Mother Brain. If done correctly, the Pikmin will increase in size along with Mother Brain as it expands. This glitch is only cosmetic, and the Pikmin will return to normal size when they come off of Mother Brain.
