Costco is selling a 5.5-pound chocolate monster head that you smash open with an included wooden mallet, and it is packed with over a pound of gummy body parts. The Ten Acre Gifts Monster Mash Chocolate, Costco item #2056395, is a hollow head molded from Belgian milk chocolate, and it has become the warehouse’s Halloween novelty of the moment.
What it is
The box weighs 88.18 ounces (2500g), which works out to about 5.5 pounds, and the chocolate is labeled 100% real Belgian milk chocolate. The head is molded to look like a green Frankenstein-style monster, and it is hollow, because the point is to break in. Ten Acre Gifts includes a small mallet, and the box promises over a pound of body-part-shaped gummies inside once you crack it open. Costco’s listing puts it at about 71 servings, so this is a party piece and a group project more than a personal candy bar.
Outlets have been calling it a “Frankenstein” head, which fits the look, though the product name on the box is simply Monster Mash Chocolate.
Price and where to find it
Costco pricing varies by warehouse and region, so there is no single national number. A Costco price tracker listed item #2056395 at about $49.99, marked down from $54.99, in early September, and trade write-ups have cited $54.99. It has sold out online at some retailers, while warehouses are still stocking it, so availability depends on your location and the week.
Why it is everywhere right now
Warehouse Halloween candy is having a search-and-social moment. Interest in Costco Halloween candy jumped sharply in the first days of September, and the broader warehouse-candy conversation, from Costco to Sam’s Club, is running hot. A five-and-a-half-pound smashable chocolate head is the kind of oversized, sharable spectacle that travels well, and it needs no haunt expertise to enjoy, which is exactly why it is showing up across feeds.
