The WereHedgehog

[TwiglettTheWereHedgehog]

is like a werewolf

occasionally (and most probably on a monthly basis) it gets a bit prickly

arf arf arf

I don't get prickly on a monthly basis or at any other time

Only monthly?

I tell myself it's monthly but I reckon if I marked it on the calendar it'd be more like weekly (or maybe it's monthly that I don't feel prickly...)
