Companion Jelly

Amorphous. The jelly can move through a space as narrow as 1 inch wide without squeezing.

Spider Climb. The jelly can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Hungry. The jelly can choose to absorb a tiny object. Metal or organic material absorbed in this way will dissolve over the course of 24 hours. The jelly can absorb up to three objects at once. As an action, the jelly can regurgitate one of its absorbed objects.

Pseudopod. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 3 (1d4) bludgeoning damage plus 6 (1d6+2) acid damage. The target is subject to Sticky.

Camouflage. The jelly is able to change its texture, opacity, and color to match those of its surroundings, becoming unseen. While camouflaged, the jelly gains advantage on all stealth checks. Camouflage is broken upon making an attack or taking damage.

Sticky.  As a reaction the jelly can choose to adhere to any object or creature it makes contact with. The subject can use its action to attempt to remove the jelly by succeeding on a DC 13 Strength saving throw. Medium or smaller creatures that the jelly adheres to have their movement speed reduced by 10 ft, while small or smaller creatures are considered grappled (DC 13). Adhered creatures have disadvantage on attacks targeting the jelly.

The adhered creature takes 6 (1d6+2) acid damage at the beginning of the jelly's turn.

While adhered, the only action the jelly can take is to release adhesion.
