Funglus grave

Fungus (see deathcap muchrooms)

Fingal's Cave is a sea-cave on the uninhabited island of Staffa, in the Inner Hebrides of Scotland. It derives its name from a legendary 3rd century Scots / Irish king, Fingal (Fionn mac Cumhail), the subject of a poem attributed to James Macpherson. It is formed entirely from hexagonally-jointed basalt, similar to that of the Giant's Causeway in nearby Northern Ireland. http://en.wikipedia.org/wiki/Fingal%27s_Cave

Therefore: Finnegan's grave
