Dwärkstones are rare rocks found underground which are capable of exploding when shaken and Blinky's choice of weapons.
When inactive, Dwärkstones look like harmless gray rocks.
However, when shaken, they begin to blink a green glow, which shows that they're about to explode.
It's one of the three ways to kill a Gruesome with the other two being flour and salt. It is activated when you shake it, and it starts glowing that means its active. After a few seconds, it will explode like a bomb.

- Running Gag: Jim, Toby, and Claire constantly misname/mispronounce the Dwärkstone as "Dork-stone".
