Woo Foo Weapons Introduced
- The Woo Foo spiral of mystic energy
- Woo Foo Book of Forbidden Evil
- This episode features Brother Herman as the main antagonist.
- This is the second episode in which the Woo Foo Armory appears.
- In a surprising plot twist, Carl the Evil Cockroach Wizard has served the role of somewhat of an anti-hero, providing Yin and Yang an escape route after they've retrieved the Book of Forbidden Evil.
- This is also the episode to feature Charles
- When Charles is captured he says "This is cruel and unusual". This is probably a reference to "The Grim Adventures of Billy & Mandy" where it is a usual transitional phrase.
