First video shows that theres a hitbox thats can make player get stuck between and can't not move their cursor until the squid moves or dies. It doesn't happen much in survival, but it is soemthing that have to be fix or people might drown.

Second show that the hitbox of the giant squid only effects it when you hit the white hit box instead of the green. hitting the mantle and arms wont make it attack you until you attack its body. Might trouble some fighters trying to killing it just to know its health isn't draining. It also shows that giant squid attack player by knocking them instead of grabbing and damaging, like what it does to guardians and fishes.

Third is this picture of giant squid getting stuck on wall after releasing itself from a cachalot whale, also realized that blue line on the hitbox when f3+B spin around too much after.

I dont know if some of this are intetional or not but, hopfully I pointed out some bugs. Thank you for reading and please fix it.
