Three Horror icons provide voices:
- Robert Englund, best known as dream stalker Freddy Krueger in the A Nightmare on Elm Street (1984) films, voices Dire Beaver and Dread Beaver.
- John Kassir, best known as the voice of the Cryptkeeper in the Tales from the Crypt (1989) television series, voices Dark Beaver and Dave Beaver.
- Bill Moseley, best known as Chop-Top Sawyer in The Texas Chainsaw Massacre 2 (1986), voices Bernie.
Bernie (Bill Moseley) uses a chainsaw as his primary weapon. Moseley's first big role was in The Texas Chainsaw Massacre 2 (1986). The chainsaw has "This Saw is Family" written on it, which "Texas Chainsaw Massacre" villain Leatherface has on his chainsaw.
The black-and-white comic book dream is a homage to the original 1984 "TMNT" comic books the franchise originated from.
"Dream Beaver" is a pun on the phrase "dream weaver".
Dire Beaver's purple color and disappearing ability is a homage to the Cheshire Cat from the dream story "Alice in Wonderland".
