Patrick Not-Star is a starfish who looks a lot like Patrick from behind, but when you face him, he has a short beard and brown eyebrows.
Patrick Not-Star looks like Patrick, except with facial hair and a nose. He has brown eyebrows, a mustache, a beard, slant eyes, and a big nose (Patrick had one until it "wilted").
He only appeared in the episode "Hide and Then What Happens?" when SpongeBob was looking for Patrick when they were playing hide-and-seek. Patrick forgot that they were playing, so he went home without telling SpongeBob. Patrick Not-Star seems to be more intelligent than Patrick. He lives in The End Of The World where he meets SpongeBob. He then asks SpongeBob for a dollar (implying that he has no money like Patrick).
