Candy Abomination

Gummy Shield. The abomination gains a shield for every creature grappled by one if its gummy worms. If a new creature is grappled by a gummy worm that player becomes a shield. If a creature stops being grappled by a gummy worm they are no longer a shield. If a shield is used up in a Gummy Block reaction they are no longer a shield but remain grappled. At the end of the abominations turned all creatures grappled by it's gummy worms become shields

Gummy Worm. The Abomination has three gummy worms protruding from its back. Each Gummy worm can be separately targeted for attacks and has an AC of 13 and an HP of 40. If a gummy worm is destroyed any creatures grappled by that worm are released from the grapple. All destroyed gummy worms regrow at the start of each of the abomination's turns at the cost of 15 HP.
