This is a absolutely JUMBO 33mm 20 sided D20 sharp edge resin dice.

This dice has a liquid core with lots of moving eyes in the dice inside which move as the dice move making it look like the literal 'Shoggoth'.

Shoggoths - are described as shapeless masses of black slime or jelly, with multiple eyes and mouths scattered across their bodies. They are considered one of the most terrifying and powerful creatures in Lovecraft's mythos. Think of this as a D20 shaped 'Shoggoth' !
