Carl

Adhesive.  Carl adheres to anything that touches it. A Huge or smaller creature adhered to the Dudethrone is also grappled by it (escape DC 13). Ability checks made to escape this grapple have disadvantage. Leonard uses his Charisma modifier (instead of Strength) and has advantage on the check to break free. He does not suffer the full effects of the grappled condition until he fails this check, at which point the Dudethrone refuses to let him up.

False Appearance. While the Carl remains motionless, it is indistinguishable from an ordinary object.

Grappler. Carl has advantage on attack rolls against any creature grappled by it.

Wheelspike. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage. This attack may be used if Carl moves in a straight line past a target. It does not provoke opportunity attacks if it hits.

Beer Shower (Recharge 5-6). Carl spews an unnaturally potent beer (from nozzles in its armrests) in a 15-foot cone or in a 30-foot line that is 5 feet wide. Each creature in the area must succeed on a DC 13 Constitution saving throw or be poisoned. While poisoned in this way, a creature has its speed halved by exposure to the potent brew. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Additionally, the beer shower extinguishes any fires or open flames in its area.

Ramscoop. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage plus the target must make a Dexterity saving throw (DC 13) or be knocked prone.
