The product is a Colorbok medium plush toy from 2002 featuring SpongeBob SquarePants characters, specifically Gary. His eyes are hard plastic.. he does not work. There is no way to open the battery without cutting into it and perhaps sewing it back up.  Perfect for fans of the SpongeBob SquarePants series, this plush would make a fun and nostalgic addition to any collection of stuffed animals or toys from the early 2000s. Please see pictures, the plush has its tags but is showing some fuzzy wear.. smoke free home.
