Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening larger than 1/2 of an inch. The swarm can’t regain hit points or gain temporary hit points.

Congeal. The swarm forms together into one medium ooze. The ooze looses the Swarm and Adhere features, gains a walking and climbing speed of 30 ft. , and gains the following action: Pseudopod. Melee Weapon Attack: +2 to hit, reach 5 ft., 1 target. Hit: 2 (1d4) acid damage. The ooze can return to being a swarm as an action.

Multiattack. The swarm makes 2 Adhere attacks.

Adhere. Melee Weapon Attack: +1 to hit, reach 0 ft., 1 target in the swarm's space. Hit: 4 (2d4 ) acid damage or 2 (1d4) acid damage if the swarm has half its hit points or fewer.. A creature hit by this attack is covered by tiny slimes and takes 2 (1d4) acid damage at the start of its turns. Removing all of the slimes requires the creature to make a DC 11 strength check as an action. Alternatively, the slimes fall off if they are dealt fire damage. If A creature is hit by multiple Adhere attacks, it takes damage from each of them at the start of its turns.
