Howard appears in "New Fish in Town" as the new neighbor of SpongeBob, Patrick, and Squidward. When he moves in In Patricks 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 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.
