A fist-sized blob of sentient mucus is bouncing off the inside of this glass jar. You can use an action to release it. When released, the blob serves you as a familiar, as if you had summoned it using the find familiar spell. It has the statistics of a frog, except its type is ooze and it can pass through an opening as small as 1 inch in diameter. You must be holding the jar to interact with the blob.
After 1 hour, when the blob drops to 0 hit points, or when you dismiss it as an action, the blob bursts, covering the ground with mucus in a 10-foot square. The area is affected as if by the grease spell (save DC 15). After the blob has burst, it regenerates inside the jar and can’t be used again until the next dawn.
