Does anyone know where I can buy an original Mr. Munch plush from Chuckee Cheese?

A few years ago, I had accidentally got rid of my dad's favorite stuffed animal/monster. It's his favorite because he bought it when I was a baby and now they don't make them anymore. I've been looking everywhere for Mr. Munch and would really love to surprise him with it. I would like to buy the plush, but if anybody knows of where I can purchase any type of Mr. Munch merchandise (new or used), I would highly appreciate the help. Thanks.
