From Horror In Clay:

"You'll love our big 10 inch...swizzle. If you, like us, love your zombies in a traditional chimney glass, these tentacled swizzles from Pickman's Cove will reach all the way to the bottom with room to spare. They are extra-strong, perfect for mixing ice and who knows what eldrich ingredients in our Horror In Clay Cthulhu tiki mug (or any other large mug you fancy). "

There is also a purple version.
