Small black uglies that escape from the dirty side of a brita filter. Usually found floating in a glass of what could be delicious water.
I puked on the front lawn today after realizing the dog dish was harvesting a brita critter.

Jill warned me not to drink from the bottom of the jug, where the brita critters dwell.
