Gizka Swarm

Medium swarm of Tiny beasts · CR 1/4
sizeMediumcr1/4
A boiling mass of tiny gizka that floods into a creature's space and bites as one, weakening as the swarm is whittled down.
Minion
How to run itMove the swarm into a PC's space and Bite; its damage halves once bloodied, so keep it on a single target and expect area attacks to thin it fast.

Swarm (Trait). The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny gizka. The swarm can't regain hit points or gain temporary hit points.

Echolocation (Trait). The swarm can't use its blindsight while deafened.

Bite (Action). Melee Weapon Attack: +2 to hit, reach 5 ft., one target in the swarm's space. Hit: 7 (2d6) kinetic damage or 3 (1d6) kinetic damage if the swarm has half of its hit points or fewer.
