Cannonball Mimic Hatchling

False Appearance (Object Form Only). While the mimic remains motionless, it is indistinguishable from an ordinary object.

 Obstreperous. If the Cannonball Mimic is restrained, grappled, or held by a live creature, and it succeeds in escaping, it does one Bite attack against the creature holding it with advantage and then escapes.

Siege Monster. The Cannonball Mimic deals double damage to objects and structures.

Death Throes. When the Hatchling dies, it explodes, and each creature within 10 feet of it must make a DC 15 Dexterity saving throw, taking (1d6) fire damage on a failed save, or half as much damage on a successful one. The explosion ignites flammable objects in that area that aren't being worn or carried.

Hopper. The Hatchling hops over any difficult terrain that is not taller than 2ft. when hopping (not dashing.)

Nimbleness: The Hatchling can move through the space of any creature that is of a size larger than it when rolling (Dashing.)

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 1 piercing damage plus 2 (1d4) acid damage.

 Impact. If the Hatchling is shot out and hits a creature the creature takes 1d12 damage, if the mimic is already deployed they can do a leap towards any creature within 60ft. if they hit they do 1d8 damage, if the attack fails, the target dodges to the side (5ft.) or crouches and the Cannonball rolls 20 more feet in the same direction or untill they hit something. If the target wields a shield, a rigid parrying instrument or heavy plated armor that gives them the AC, they can use that to deflect it in which case it bounces away 20ft in another direction.
