The mountain looks like a cliff rather than an actual mountain. The mountain is sand colored and has a purple rocky side that drops straight down.
The mountain appears in "Valentine's Day" during the Valentine's Day Carnival when Patrick was guessing what his Valentine's gift from SpongeBob was. Patrick runs up the mountain and falls off hoping his gift is there. It also appears in the video game Employee of the Month in the background of a level on the PC version of the game.
