Patrick Star is a main character in SpongeBob Squarepants. He is a friendly yet sometimes aggressive starfish and SpongeBob's best friend. He and SpongeBob have apparently known each other since infancy, and they share many interests (jelly fishing, Mermaid Man and Barnacle Boy, bubble blowing, etc.). Patrick is highly unintelligent, and he often convinces SpongeBob to accompany him in dangerous or fruitless activities, such as playing near fish hooks and eating whole pumpkins.
