Multiattack. The su-monster makes two attacks: one with its bite and one with its claws.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) slashing damage, or 12 (4d4 + 2) slashing damage if the su-monster is hanging by its tail and all four of its limbs are free.

Psychic Crush (Recharge 5–6). The su-monster targets one creature it can see within 30 feet of it. The target must succeed on a DC 11 Wisdom saving throw or take 17 (5d6) psychic damage and be stunned for 1 minute. The stunned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
