Howard wears glasses with golden frames and wears a green polo shirt. He is mostly seen with his bassoon. He is violet in color and his dorsal fin is light blue. He has three dark purple spots on the top of his head.
Howard is very much like Squidward, he is very intolerant and is interested in music and art. Later on in the episode, Howard stops being "stuffy" and befriends SpongeBob and Patrick.
When he moves in Patrick's front yard, he quickly becomes Squidward's best friend but when they first met, he doesn't really like him. During most of the episode, Squidward tries his best to keep Howard from noticing SpongeBob and Patrick. Howard later ended up acting like SpongeBob and Patrick which annoys Squidward into sending his house off a cliff while Howard jumps after it and it is known that he may come back to live there.
Howard is the only known character that plays the bassoon.
