Aromamorphous. The ooze can move through a space as narrow as 1 inch wide without squeezing, provided it leaves its mug behind.   Daily Grind. If the ooze dies while inside a mug or similar container, it reforms after 24 hours and regains all its hit points. Only a wish spell can prevent this trait from functioning.   Flavorful Appearance. While motionless, the ooze is indistinguishable from a cup of coffee or similar liquid. It can choose to appear spilled.   Perfect Blend. During a short rest, the ooze can magically bond with a willing creature within 5 feet. The bond lasts until either the creature or the ooze dies. The ooze can only be bonded to one creature at a time.
While within 5 feet of the ooze, the bonded creature can take a sip as a bonus action and expend one Hit Die. If it does, it rolls the die and adds both its Constitution modifier and the ooze’s Constitution modifier (+3), regaining that many hit points. Any excess healing becomes temporary hit points. If the creature expends its last Hit Die this way, it regains no Hit Dice at its next long rest and it cannot be rendered unconscious for 6d4 hours.
The bonded creature must take a sip at least once every 12 hours or gain one level of exhaustion. A non-bonded creature that drinks the ooze must succeed on a DC 10 Constitution saving throw or take 2 (1d4) acid damage.
