Yoshi is a character in Boo Party 8.
Yoshi is some normal person playing Mario Party. However, Birdo has a crush on Yoshi. Boo, knowing this, always tries to ruin things for the two. From appearing in front of the two showing his penis at them, then claiming "that's how Birdo acts in public", to photoshoping Birdo pictures to make them stupid and unimpressive. (EX:A picture of Birdo doing 9-11)
