Princess Ebonmire and Prince Livid

Princess Ebonmire and Prince Livid are two characters that appear in Dungeons and Dragons. They are oozes that gained some sentience from Juiblex's incursions. Their guardian, the Pudding King, took them in as his children after his exile from Svirfneblin-kind.

Description
Princess Ebonmire is a sentient black pudding. Her attacks include hurling blobs of her sticky substance, though she can also engage in melee.

Prince Livid is a gray ooze that has access to psionic powers. He is smarter than his kind, just like his female counterpart.

Combat
In combat, Princess Ebonmire engages in melee. Prince Livid uses her body to shield himself as he recharges his psychic crush attack. Once she is defeated, Princess Ebonmire surrenders a spellbook that can resist being damaged by acid.
