Squidward's Self-Portraits are artworks by Squidward that are seen in a lot of episodes involving his house. One of Squidward's most famous paintings is a portrait of a clown. Squidward's Self-Portraits are first seen in the episode, "Opposite Day."
Squidward's Self-Portraits seems to change locations in different episodes. In "Opposite Day" and "Squid's Visit," they are located upstairs. In "Not Normal," they are located downstairs in the living room.
In the episode "Squid's Visit," SpongeBob managed to copy Squidward's entire wall of self-portraits. Squidward admits that they were even better than his.
"Squid's Visit" is the only episode that has a screenshot of over one hundred paintings.
In "Not Normal" Squidward has 483 self-portraits, but in "Squid's Visit," he has 492. This possibly took place after "Not Normal," or he took 9 of them out in order to save room.
In "Squid's Visit," there is a self-portrait of a sad crying clown, but this painting frightened many younger viewers, which is another reason they call this episode "creepy."
One of Squidward's paintings resemble one of Picasso's paintings.
The backgrounds of the portraits come in red, green, brown, magenta, pink, purple, lime, orange, scarlet, blue, indigo, turquoise, black, light blue, yellow, pale and dark green.
