Bollogg Fleas. Of all the large bloodsucking insects in Zamonia, Bollogg Fleas must undoubtedly be the biggest. They can attain a height of eighteen feet and weigh three-quarters of a ton. Bollog Fleas have a wingless, lopsided body and powerful legs that are admirably suited for jumping. Sprouting from the head are two long antennae for examining prey by touch, and beneath them are a pair of sawlike mandibles and the proboscis with which Bollog Fleas immobilize their victims and suck them dry. Their favourite habitat is the dense hair on discarded Bollogg heads. They feed mainly on smaller mountain creatures and unsuspecting mountaineers.
