Kelpy G is one of the famous clarinet players that Squidward dreams of being like. He seems to be a very mellow squid who believes in peace and tranquility. He only 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.
Kelpy G. looks like most squids do, tall, teal, with four legs. He has long, light brown hair, and a black mustache. He wears an orange, long-sleeve shirt with a red stripe on it. In Smoothe Jazz at Bikini Bottom he wear shoes that look like SpongeBob's.
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 performs concerts for Squids too.
