Prawn is a long blue shrimp with a mustache, a big nose, black tuxedo, two arms and feet, and a tail.
Prawn has appeared in two games in the SpongeBob series. He first appears in Battle for Bikini Bottom, where he forces SpongeBob to fight him. In this game, he is the same size as Plankton and carries a large backpack with a large tube on it. During the battle, Prawn's primary attack is sending sound waves toward SpongeBob that he must jump over to avoid damage. He is also surrounded by the blinking panels seen in earlier parts of the Mermalair. When Prawn's health gets lower, he summons Ham-Mers to aid him in battle. The only way to defeat Prawn is to wait until the panels on the ground form a straight line and SpongeBob must use his Bubble Bowl technique to damage him by rolling one down the panels that are unlit. Prawn must be damaged three times to be defeated.
He reappears briefly in Truth or Square inside a giant glass jar in the Mermalair. He was located in the exact spot where he was defeated in the previous game. In this game, he is referred to as Man Ray or Dr. Shrimp by SpongeBob for unknown reasons, but SpongeBob is fooled and is identified as Prawn.
