He also usualy wears blue overalls with two golden snaps along with a brown farmer hat. This is his most notable appearacnce ever since "High Sea Diving."

Antagonistic side

  • In "The Sponge Who Could Fly," SpongeBob accidentally causes accidents for Old Man Jenkins, causing him to change his profession, from Farmer to Sailor, and then to Cannonball, where he shoots SpongeBob down.
  • In "High Sea Diving," Old Man Jenkins tricks the Bikini Bottomites into believing he is King Neptune and proclaims himself as ruler of the sea. However, this was brought on because he was trapped up there by his friends. He also tried to tell SpongeBob to leave, since he was trying to stop him. After the garbage fell into the city, he attempted to pose as Neptune again while the people were hurt from the fall. When the real King Neptune appears on the scene, he receives his karma since the latter is not impressed with the lies and impersonation Jenkins has done. As punishment for his actions, Neptune zaps the deluded old man with his trident, burning him to a crisp.
  • In the SpongeBob SquarePants musical, Old Man Jenkins leads an angry mob against Sandy after believing she was the cause of the volcano about to erupt.

The name is always referred to elderly fish.

He reveals that he accidently ended up at the surface by getting pulled up by a bunch of balloons.

In the end of the episode, when Patrick reveals to have taken a bath after being kicked out of the Krusty Krab and is in his bath clothes, Old Man Jenkins gets frightened.
