He was a cherry red ice pop with eyes, eyebrows, and a mouth identical to that of Patrick's. He has two sticks for legs.
CreamBob ConePants introduced him, along with the other main ice cream-themed characters, to SpongeBob and Patrick. It is then implied that he, along with everyone else in Pint Bottom, was eaten by SpongeBob and Patrick.
His name is a pun on "Patrick" and "Popsicle," which is a popular brand of flavored ice.
