Chargin' Chuck

Chargin' Chucks are Koopa football players that use various sports equipment as weapons, and are seen only in Super Mario World. They have many offensive attacks, such as charging, jumping up in your way, and signaling Rip Van Fish and Super Koopas to attack. They also throw baseballs straight ahead, and kick footballs that ricochet off the walls and ground. One strange type digs up small boulders that bounce. If they aren't charging, and you step on their heads, they'll become angry and run at you.

Twirling your cape stops the baseballs and can defeat them. Unfortunately they're too big for Yoshi to eat.

Chargin' Chucks appeared in The Adventures of Super Mario Bros. 3 where they were just called Football Players. They also appeared in the Super Mario Adventures comic.
