Grassland Camouflage. The swarm has advantage on Dexterity (Stealth) checks made to hide in grassland terrain.

Keen Smell. The swarm has advantage on Wisdom (Perception) checks that rely on smell.

Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny pygmy cheesum. The swarm can’t regain hit points or gain temporary hit points.

Aᴄᴛɪᴏɴs

Multiattack. The swarm makes two melee attacks, one with its bites and one with its claws.

Bites. Melee Weapon Attack: +2 to hit, reach 0 ft, one target in the swarm’s space. Hit: 9 (2d8) piercing damage, or 4 (1d8) piercing damage if the swam has half of its hit points or fewer.

Claws. Melee Weapon Attack: +2 to hit, reach 0 ft, one target in the swarm’s space. Hit: 10 (2d6) piercing damage, or 3 (1d6) piercing damage if the swam has half of its hit points or fewer.

The pygmy cheesum, despite its precious appearance, is a vicious predator that attacks in swarms. It feigns death (non-magically) when it believes itself in danger. When chasing prey or evading a predator, its natural speed often protects it.
