The mom and dad in the station wagon in the teaser opening look exactly like Ellen and Clark Griswold, who drove that exact same car in National Lampoon's Vacation (1983). The mom is voiced by Beverly D'Angelo (who played Ellen in all of the Vacation movies), while the dad is voiced by a Chevy Chase sound alike (Chevy played Clark in all of the Vacation movies).
In the backstory behind Gatorsburg, the prospector that discovered the gators is Nugget Nose from Buford and the Galloping Ghost (1978).
