CTAN Update: halloweenmath
Added bats, skulls, and quite a lot of extensible arrow-like symbols (including, but certainly not limited to, fluttering bats…). In certain symbols, moreover, the shape of the brooms has been enhanced.

halloweenmath – Scary and creepy math symbols with AMS-LaTeX integration
The package defines a handful of commands for typesetting mathematical symbols of various kinds, ranging from ‘large’ operators to extensible arrow-like relations and growing arrow-like math accents that all draw from the classic Halloween-related iconography (pumpkins, witches, ghosts, cats, and so on) while being, at the same time, seamlessly integrated within the rest of the mathematics produced by (AmS-)LaTeX.
