The Bearsharktopus makes one bite attack and one tentacle attacks, each of which it can replace with a use of Fling.  

Bite

Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit 20 (2d12+7) piercing damage.  

Tentacle

Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit 29 (4d10+7) bludgeoning damage and the target is grappled. Until this grapple ends, the target is restrained. The Bearsharktopus can grapple one target with each tentacle it possesses.  

Fling

One Medium or smaller object held or creature grappled by the Bearsharktopus is thrown up to 40 feet in a random direction and knocked prone. If a thrown target strikes a solid surface, the target takes 1d8 bludgeoning damage for every 10 feet it was thrown. If the target is thrown at another creature, that creature must succeed on a DC 18 Dexterity saving throw or take the same damage and be knocked prone.
