I LOVE Halloween. And I LOVE the red bases during Halloween. But there's so much more to Halloween than red and evil. I thought of the graveyard encounter in explore and thought maybe this could be a rare drop.

Name: Memoriam, Tombstone, Mausoleum

EDIT: whew now that that coding unpleasantness is done lol, It's meant to be a

Or a

It's meant to look like an old, cracked, weathered tombstone.
Edit 2: there could also be markings, rather than a solid base.
