The term 'monstrous creature' can refer to two different creatures: the BEHEMOTH and the BEAST. The BEHEMOTH is a biblical creature described in the Book of Job as an enormous land animal, often interpreted as a hippopotamus or elephant. The BEAST is a creature from Greek mythology, often depicted as a hybrid of several animals, such as a lion, goat, and serpent. Both creatures are known for their immense size and strength.
