Limited Amphibiousness. The shark with a knife can breathe air and water, but it needs to be submerged at least once every 4 hours to avoid suffocating.
“Oh Shit, It’s—”. Any creature that starts its turn within 60 feet of the shark with a knife that can see the shark with a knife must succeed on a DC 10 Wisdom saving throw or become frightened until the start of its next turn. On a successful saving throw, the creature is immune to this trait for 24 hours.
Shark With A Knife Theme Song. When the shark with a knife moves it can repeat the phrase “duh nuh… duh nuh…” over and over again, increasing the tempo as it moves closer to a target. So long as the shark with a knife continues doing this, then moves 20 feet straight and hits the target with a knife attack on the same turn, the target takes an extra 2 (1d4) piercing damage.
Multiattack. The shark with a knife attacks with its knife. If its knife attack hits it can use its bonus action to make one bite attack.
Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.
Knife. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 4) piercing damage. If the shark with a knife hits, it yells “BOOM!” This declaration of BOOM has no effect other than just being really loud and weird.
