Charlie the Pillow is a character that only appeared in the episode "Extreme Spots."
He is a light bluish-white pillow who can talk.
Charlie the Pillow was used as a fighting object in which SpongeBob tries to wrestle in a ring, but he does not end up accomplishing it. Johnny Krill then shows SpongeBob on how it is done. He elbows the pillow and he puts the pillow into a washing machine, then sets it on wash. While the pillow is in the washing machine, Johnny Krill opens, takes the pillow and punches the pillow out of the wrestling ring. While lying down on the ground after getting punched, Charlie the Pillow tells his Mattress friend to avenge him.
