look up any word, like dog in the bathtub:
A Fleefloose is a feathery, fat flying creature that burrows itself into chimnies and ceilings.

It flies down the chimney at night and scavenges on anything that it can find. Such as beanbags and mouldy food. It mainly lives in the city because it can find most of its food there.
It originally started off as a Meemoos but slowly evolved wings but comprimised them for good claws.
