Christmas tree

From The Maze Where Realities Converge - the psychedelic encyclopedia of reality from The Ultimate Comment

A central point on which all Christmas feeling tone gets focussed. Christmas trees are the precursor to the dimensional transfunctioner, they are smaller transfunctioners, which is why they can only be present for a small portion of the year. Otherwise there would be too many vortices.

When they dry out, you can set fire to them (accidentally or deliberately) and it looks cool. Trust us, we know.
The flaming Christmas tree is the official weapon of the Miaowjahideen, because it can be used in any combat from annihilating entire civilizations to one-on-one fights.
