Multiattack. The otyugh makes two attacks: one with its bite and one with its tentacles.
Bite. Melee Attack: 1d20+6 to hit, reach 5 ft., one target. Hit: 12 ( 2d8+3 ) Piercing Damage. If the target is a creature, it must succeed on a DC 15 Constitution saving throw against Disease or become Poisoned until the disease is cured.
