how well can you guess the trevor henderson creatures?

the Sea eater is said to be 25 km (about 15.5 miles) long, bigger than a ship

correct, this is false. long horse is known as guardian or protector of humans

Day 17 is a wandering creature, it is highly hostile to you if you are unworthy, if you are deemed worthy, it will be benevolent and lift you with its massive tendrils and bring you to "heaven"

watchtower is a benevolent creature. she is a protector of a small towns and guards it from threats, she is also apart of "the giants" but acts as their adversary rather then an ally

this creature is known as the "thing in the stairs' or "friend upstairs". it's not hostile but it does create an uneasy thing like extreme paranoia and psychological stress

The creature's name is "the good boy"

think of a creature that is highly dangerous but not malevolent
