1. This creature has 4 different types of attacks. I'd want to showcase that.
As written, it doesn't. That sucks.
Also, Swallow doesn't work with multiattack.
2. I like the LR involving dropping a creature.
So first I'd modify it.
...
Give it 4 legendary actions, which are ... all tentacle attacks. (4 tentacles? Get it?)
Maybe have a subsystem where it loses tentacles. A legendary resist can lose a tentacle!
As it loses tentacles, it starts to frenzy.
Multiattack being a bite and a tail smash is good. But I might also add in a tentacle there as well; 1 of each.
"The shark bites a creature, makes a tentacle attack (if it has any left) and then does a tail smash on creatures it didn't try to bite".
Tentacles: The tentacle shark has 4 tentacles. They regrow after a short rest. If the shark suffers a critical hit, it loses a tentacle.
Legendary Resists (4): If a Tentacle Shark fails a saving throw, it can sacrifice a tentacle to instead save. If it does so, one random creature held by its tentacles is released.
Frenzy: When the Tentacle Shark makes a Bite attack, its Bite damage increases by 1d10 for every tentacle lost, and if it misses, it can make an attack on a different target with its Bite (at most tentacles lost extra attacks).
Bite: Damage reduced to 1d10+5.
Tail smash: I'd cut the 1d6 bludgeoning. Too much stuff to remember, not that dramatic.
Swallow: Happens automatically if it Bites a creature it has restrained.
Tentacle: Restrains creatures.
Blood in the Water: The shark has advantage on perception checks against creatures with less than full HP, and has advantage on attack rolls on creatures with less than half of max HP.
Legendary actions:
Has 4 legendary actions. Every time it loses a tentacle it loses a legendary action.
Detect: The shark makes perception check and then makes a tentacle attack.
Speed of Sekolah: The shark moves its speed and then makes a tentacle attack.
Thrashing Tentacles (2 actions, at most 1/round): ... and then makes a tentacle attack on up to 2 different creatures.
