What's his problem?
— Incidental 90, "Mid-Life Crustacean"

Incidental 90 is an elderly fish who debuts in "Mermaid Man and Barnacle Boy." He is likely classified as an "elderly" type incidental.


He is a dark tan fish with a light tan dorsal fin, with dark red spots on his head. He wears light red and light blue boxers. He also has an underbite.

Role in series

Incidental 90 at the Krusty Krab.

Incidental 90 is a very occasionally used incidental character due to most elderly incidentals being portrayed as residents at Shady Shoals Rest Home. He also has very few notable appearances as well. He currently has had only one speaking role in the series so far.

Major roles

"Mid-Life Crustacean"

He is seen in the long line in front of the ice cream stand in front of the Cemetery. He questions what Mr. Krabs' problem was when he ran away yelling "I'm not old!"

"Gullible Pants"

Mr. Krabs considers putting Incidental 90 in charge of the Krusty Krab while he is away, but quickly declines in because he is "too lumpy."

"Super Evil Aquatic Villain Team Up is Go!"

He is seen dancing with Incidental 82 at the Ladies' Choice dance until she leaves him to go dance with SpongeBob.
