A chocolate Frankenstein head filled with gummy candy being sold for more than $50 at Costco is going viral on social media.

The hefty Halloween treat weighs 5.5. pounds and includes a mallet to smash the monster’s head and get at the gummies, which are shaped like body parts.

The "Monster Mash Chocolate" made by Ten Acre Gifts sells for $54.99 at the wholesaler and for more than $60 online, although it appeared to be sold out on Costco’s website Saturday evening.

While some Halloween fans were in love with the chocolate treat, others thought it was a little over the top.

One person on Instagram said they would consider it if they were hosting a Halloween party and another commented: "Hard pass but would make a great prank Christmas gift."
