Book of Infernal Demons
"A royal inhabitant of Inferno. Concealing her form under most circumstances, she appears as a gigantic toad when summoned.

Baal's enormous, wobbly body is too heavy for her to control, giving her a disadvantage in the heat of battle; however, she possesses an endlessly extending tongue that can reach the far ends of the battlefield and swallow up opponents within an instant."
