Patrick Not-Star is a starfish who looks a lot like Patrick from behind, but 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, brown hair, a mustache, a beard, slant eyes, and a big nose (Patrick had one until it "wilted").
He only appears in the episode "Hide and Then What Happens?" when SpongeBob is looking for Patrick when they are playing hide-and-seek. Patrick forgets that they are playing, so he goes home without telling SpongeBob. Patrick Not-Star seems to be more intelligent than Patrick. He is seen at The End of the World where he meets SpongeBob. He then asks SpongeBob for a dollar (implying that he has no money like Patrick).
