Costco’s 5.5-pound chocolate Frankenstein head filled with gummy candy goes viral at $54.99

Costco shoppers are paying $54.99 for a 5.5-pound chocolate Frankenstein head this Halloween season, a product called Monster Mash Chocolate that comes with its own mallet for smashing the shell and reaching the gummy candy inside, according to Foxbusiness. The treat, made by Ten Acre Gifts, appeared to be sold out on Costco’s website by Saturday evening, even as listings elsewhere pushed the price above $60.

Key facts

• The Monster Mash Chocolate head weighs 5.5 pounds and sells for $54.99 at Costco.
• It is made by Ten Acre Gifts and includes a mallet to break open the chocolate and reach gummy candy shaped like body parts.
• The label lists 150 calories per serving and 25 servings per package.
• Listings online priced the item above $60, and it was selling on eBay for as much as $100, according to Foxbusiness.
• The product appeared sold out on Costco’s website by Saturday evening, the report said.

A hefty Halloween novelty built for sharing

The product sits in a familiar Costco pattern: a seasonal item that is oversized, interactive, and priced low enough per serving to feel like a value relative to its sticker price. At 25 servings of 150 calories each, the chocolate head is designed less for one person than for a party or a family gathering, which is likely why some of the social media reaction focused on whether the treat justifies the counter space.

Reaction on social platforms split between enthusiasm and amusement. On Instagram, one commenter said the purchase would only make sense for someone hosting a Halloween party, while another called it something they would skip but consider as a gag Christmas gift. On X, the jokes leaned on the built-in hammer, with users describing the concept as a medically alarming version of a piñata and questioning the logic of packaging a demolition tool with candy.

The attention follows a broader run of Costco products that have moved quickly from warehouse shelves to viral status, a pattern that has occasionally sent shoppers to resale markets. The chocolate head followed that path as well, with eBay listings asking as much as $100 according to Foxbusiness, well above the wholesale club’s price and the online asking prices above $60.

Why it matters

For Costco, limited seasonal items like this function as both a margin-friendly impulse buy and a marketing engine, generating social media attention that no advertising budget buys directly. For shoppers, the practical effect is the same dynamic seen with other viral warehouse products: once an item trends, availability narrows, and resale listings can push the effective price well above what the club charges. Ten Acre Gifts, the manufacturer, benefits from that cycle without needing a national ad campaign.

What to watch

Whether the chocolate head returns to Costco’s website stock and whether the club responds to Foxbusiness’s request for comment will determine if this stays a brief seasonal curiosity or becomes another recurring Halloween staple. Its price on resale platforms is the clearest live signal of demand, and those listings typically soften once supply catches up.
