It's the wrong part of the world, but the spikes look like that of a Floss Silk tree:

I've a few around my house and the resemblence seems close. Unfortunately they are tropical from South America. Maybe a relative of some kind lives in the Philippines? That is of course unless the spikes are carved, then it's just a coincidence...
