Character biography

Patrick is a pink starfish and SpongeBob's best friend. He and SpongeBob have apparently known each other since infancy, and they share many interests (jellyfishing, Mermaid Man and Barnacle Boy, bubble blowing, etc.) It is revealed in the episode "Rule of Dumb" that he and Spongebob's pet snail, Gary, are cousins.
Patrick is very unintelligent. He often convinces SpongeBob to accompany him in dangerous or fruitless activities, such as playing near fish hooks and eating whole pumpkins. In spite of the disastrous outcomes of Patrick's ideas, SpongeBob constantly attests to Patrick's genius, and consults the starfish for advice and guidance.
Patrick has no job or trade and spends most of his time sleeping or playing with SpongeBob. When he tries to find work, it is shown that he has little practical skill, for example in "Big Pink Loser", he struggles with tasks such as sweeping or opening a jar.
Patrick's manner is very childlike, though, like SpongeBob, he prides himself on his self-proclaimed "manliness". Like his friend, he enjoys things that are considered "babyish", such as large lollipops and homemade cookies. Though Patrick is generally kind and friendly, he will, when provoked, go into rages, generally screaming his demands and occasionally attacking those around him.
