There are some things I've not really heard of before, and those are the ones I'm after right now.
Take a look at the Sigbin, at least according to this site:
Sigbin is a creature is said to come out at night to suck the blood of victims from their shadows. The creature walks backward with its head lowered between its hind legs. It resembles a hornless goat, emits a very nauseating smell and possess a pair of very large ears which are capable of clapping like a pair of hands.It is also claimed to issue forth from its lair during Holy Week, looking for children that it will kill for the heart, which is made into an amulet.I like this one because it's just plain freaky.

the website of that excellent Filipino Urban fantasy/horror
comics series Trese, whose website is here.
The amulet is interesting -- it provides a reason for hunting the creature down. It also makes it a moral issue for those who are after whatever powers this amulet grants, given the source.
