Noun. A rabid squirrel that runs around in the dark and stores optics in its cheeks. Has absentminded tenancies and can be identified by its crazy physics hair. May also have a nearby stash of useless gadgetry, often kept in the ceiling tiles.
The Andri could be spotted popping in and out of its squirrel cave.
The Andri is often hunted by Billys whose weapon of choice is the inflated latex glove.
The Andri can be observed in its natural habitat, being bossed around by its offspring.
