Wendy O. Koopa

Wendy O. Koopa sometimes known as Wendy Koopa is the only female Koopaling who appears in the Mario games. In SMG4, she makes cameos in several videos but her major appearance wasn't until very recently in SMG4: Stupid Mario World where Bowser Jr. sends her and her brothers to pummel Mario and Yoshi. Wendy is seen in the underwater area riding a Sushi taunting Mario and Yoshi from below but Mario and Yoshi manage to easily defeat Wendy by throwing an Amp in the water electrocuting her, the Sushi, and all the fish in the water. Mario and Yoshi then continue to Rainbow Road.
