Unsurprisingly, the Puckstone’s alternative name is the Fairy Stone. Heaths can be weird places.
The stone is marked on the 1:25000 map – perhaps juamei missed it because he wasn’t in quite the right spot? It’s north of the Agglestone, right by a track. It’s the same type of rock as the ‘holy’ stone, but apparently with a scarier reputation.
