- Although the villain names "Alvin" and "Arvin" are very similar, they have nothing in common.
- According to the book LarryBoy and the Abominable Trashman, Alvin is afraid of the dark, polyester, and chickens. The latter was caused by a chicken mistaking his head for an egg and sitting on it when he was five years old.
- Alvin is one of the few LarryBoy villains to have natural limbs, the others being The Fib, the Rumor Weed and Gunkzilla.
