I've made a decent creepypasta about the random patches of
already carved pumpkins scattered throughout Minecraft.
To sum it up without the scary portion:
Imagine that recently before you awoke there were inhabitants lurking on Minecraft. When great ravines warped the earth and a fissure tore across its landscape they ran from something which required them to wear pumpkins to hide their faces. You later find the remanence but no bodies.
