Strainbeansucker

The Strainbeansucker evolved from the Uksip Marfinnus. It lives like a leech on the giant Strainbeans. With its long spike, it pierces the Strainbean and gulps its blood, leaving a wound. Once a Strainbean is pierced, the Strainbeansucker never leaves it on its own, except for when the Strainbean dies, but the lifespan of a Strainbean is much longer than that of the Strainbeansucker, so a few generations of Strainbeansuckers will pass before the host dies. Sometimes, when a Strainbeansucker can't find a Strainbean, it attaches itself to other bigger animals. Because of their skin color, they're very hard to see on a Strainbean.
