Slugger

Sluggers, also referred to as a Baseball Boy Slugger, are a type of yellow Bandit that first appear in Super Mario World 2: Yoshi's Island that often appear alongside Green Gloves as part of the Baseball Boys. Sluggers use their baseball bats to return eggs that Yoshi throws at them, which will push Yoshi backwards upon contact, but can also be jumped on. This mechanic is occasionally used as a method of obtaining certain Smiley Flowers. As well as returning any eggs thrown at them, Sluggers will also return Chomp Rocks and seeds spat from a Watermelon. Sluggers cannot be grabbed by Yoshi's tongue, but can be defeated by Ground Pounding or jumping on them thrice. Sluggers later appear in the remake of the original game, Yoshi's Island: Super Mario Advance 3, and also in Yoshi's Island DS, in which they act identically to the first game.

In Super Smash Bros. Ultimate, a Slugger and a Green Glove appear as a spirit.

 * Shogakukan guide: タマゴを投げると打ち返してくる. 倒し方はミットさんと同じ. (When you throw an egg, it hits it back. The way to beat them is the same as Green Glove.)
 * Player's Guide: This wannabe loves it when you throw an egg right across the plate.

Yoshi's Island: Super Mario Advance 3

 * Shogakukan guide: タマゴを投げると打ち返す. このタマゴに当てってもダメージは受けないが、強くはじき飛ばされてしまう. ３回ふむか、ヒップドロップで倒そう. (If you throw an egg at it, it will hit it back. If the egg hits you, it will not damage you, but it will bounce off you strongly. Step on it three times or use a Hip Drop to take it down.)
