Red Mist Squidward

Red Mist Squidward, abbreviated as RMS, is a minor character in Spongebob Squarepants. He is an alternate-universe version of Squidward Tentacles who lives behind one of the many mysterious doors in RandomLand. He appears in The RMS Halloween Special! as well as the uncut version of the episode "SpongeBob in RandomLand." But he was later replaced by a baby version of Squidward.

In the UK and future United States airings (starting in November 2019) and international digital version of "SpongeBob in RandomLand," the scene featuring Red Mist Squidward was cut due to a Standards and Practices issue, with the clip being replaced with a short animation of Baby Squidward. However, the original version of the scene remains on the Nick app version of the episode and, as of December 2019, Canadian airings on YTV.

In response to the censorship, Paloian stated, "It's actually kind of fun that it got censored."

Description
He is a "scary" version of Squidward. His head is the only part of him that is shown. He is a turquoise octopus with the same head shape as Squidward. Unlike Squidward, his eyes are bulging and circular. He has black pupils and scarlet-red irises, unlike Squidward's rectangular maroon-red pupils. Red Mist Squidward's defining trait is that he has bleeding black mascara around his eyes.

Role in episode
Red Mist Squidward lives in RandomLand in an empty bedroom identical to Squidward's room.

When SpongeBob and Squidward go to RandomLand, they find a wall of doors. Squidward tries opening them and finds strange, warped versions of himself and SpongeBob. In one of the doors, Squidward finds what looks to be his bedroom, before it is quickly replaced by a background of TV static. Red Mist Squidward then appears in front of it, staring menacingly. Squidward quickly closes the door, terrified.
