Karate Gear is used by SpongeBob and Sandy in all episodes involving Karate (excluding "Karate Island"). Karate Gear consists of two items: a horizontal helmet (only for SpongeBob) and big gloves. SpongeBob's are red and Sandy's are green. The gear is used to protect them.
SpongeBob's karate gear is red-colored. His gear helmet has a ladybug design on the left-side hole, as seen in "I'm With Stupid." His gloves are big. In the Nicktoons Unite! games only his gloves appear.
Sandy's karate gear is usually green-colored; however, in the episode "Waiting," she wears red, and in the episode "Sandy's Nutmare," she has pink karate gear. She doesn't wear a helmet, as she has her own air helmet. Just like SpongeBob's gloves, hers are also big.
Patrick's karate gear is just like SpongeBob's, except it is blue instead of red, and his helmet is a little smaller. It is seen in "Karate Star."
