During production, Producer Sue Bea Montgomery showed little kids some concepts for the movie and watched the expressions on their faces. Since they especially liked the character of Japeth the Goat, they decided not to delete him, as they had initially planned.
The character of "The Wolf" seems to be patterned after Chevy Chase's "Fletch" character. He's an investigative reporter, uses disguises to get information and even his theme music is very much like what you hear in Fletch (1985).
In Red's story, when she and Japeth are riding the mine cart, for a few frames, you can see Wolf and Twitchy riding past in a different mine cart. Later, in Wolf's story, while recounting the same time period, you can see Red and Japeth for a few frames in the background.
After Kirk the Woodsman gets his call back, Tommy, the lizard director says, "I have to be in a circle wipe, across town." A circle wipe is an effect in television and cinematography in which an image appears as a dot in the center of the screen, then expands to full size while overlaying the preceding image. This is exactly how Tommy appears on the screen when talking to Kirk.
During the interrogation, both Red and Wolf are offering different versions of the same story. Both insist they are innocent of wrongdoing, and both are wearing hoods (Wolf is wearing an athletic hoodie). Both their hoods are primary colors. In every way, they are in competition with each other.

The trivia items below may give away important plot points.
The scene where Boingo is admonishing his henchman, Keith, that his name isn't scary enough and he should change it to Boris, was not scripted. It was ad-libbed by Andy Dick while recording his lines. The dialogue is ironic because the names mean almost the same thing. Keith is Scottish-Gaelic and means, "from the battlefield". Boris is Slavic, and means, "battler, or, warrior".
During the scene when Mr. Flippers is explaining who the Bandit is, and Granny is signing Boingo's clipboard, on the other side is a list of things to do, which are: Take down Muffin Man, Ruin Red, Act cute & fuzzy, Steal Recipe Book!!, Send Wolf on goose chase, Pick up dry cleaning, Pay evil ski team, Pay gas bill, Call Mom, and Finish lair.
Boingo says that he was asked to join Mensa. The Mensa website reads, "...potential members must score within the top two percent of any approved standardized intelligence test". Using statistical averages, this means that Boingo's I.Q. is in the range of 140.
Granny's extreme sports name "Triple G" is a spoof of the Vin Diesel movie Triple X where he plays an extreme sports athlete with the nickname of "Triple X". The three G's she has tattooed onto the back of her neck, is a spoof of the three X's Xander has on his neck.
