Kelpy G is one of the famous clarinet players that Squidward Tentacles dreams of being like. He seems to be a very mellow octopus who believes in peace and tranquility.
Kelpy G's appearance is like most octopi in the show: tall and teal with four legs. He has long, light brown hair, and a regular brown mustache. He wears an orange, long-sleeve turtleneck with 3 red stripes on it. However, in "Smoothe Jazz at Bikini Bottom," he wears shoes that look like SpongeBob's and wears a long purple dress shirt.
Kelpy G has his very own TV show where he performs smooth jazz. He also performs smooth jazz for the Smellies; he calls them "his children," suggesting that he's their leader.
He appears in the episodes, "The Thing" and "Smoothe Jazz at Bikini Bottom," performing a jazz song on Squidward's TV and performing a concert. Squidward is annoyed that SpongeBob and Patrick keep interrupting while he is trying to listen to Kelpy G play. Squidward attempts to meet Kelpy G but gets kicked out as SpongeBob plays with the musician.
