Fridge Logic: In the 7-minute short "Falling To Pizzas", Calamity is unable to purchase pizza selling for $1.50 a slice — yet is apparently able to purchase gadgets as expensive as a solar-powered helicopter from the Acme Shopping Network! One wonders if he holds a credit card that can only be used exclusively for Acme products...
Fridge Brilliance: The show practically has No Fourth Wall, so it makes sense that Calamity, modeled after Wile E. Coyote, would have considerably less trouble getting Acme products than his inspiration did. After all, technically Wile E. should have had to pay for shipping, too, while Calamity can probably just go to the AcmeMart.
In Going Up, the mall thief that Baby Plucky encounters is the chainsaw maniac from How I Spent My Vacation, which means Plucky is the reason he went off the deep end, and he recognizes him after all that time.
Fridge Horror: Gogo is the son of the original Dodo. He's also referred to as "last of the dodos" and his father is never seen on screen. This implies that his father is dead.
Fridge Brilliance: Why does Acme Looniversity have a Spotlight Stealing class? Because it was built by Bugs Bunny, who stole the spotlight from Daffy Duck as the star of the original Looney Tunes.
