Spider Lair (a)

Although the outer defense of these monsters was so strong that even a magic emperor couldn't penetrate it, they were as soft as tofu from the inside. Outwardly, they were sturdy like a masculine man, but inwardly, they were soft like a female's buttocks. After flipping them to the back of their super shells, a sadist like Elliot used their weakness to his advantage and abused their bubbly buttocks like innards and inner organs to the best of his capabilities.
