The track layout

Wacky Worm, also known as Big Apple, is a roller coaster layout produced by many different manufacturers.

The first model to use this layout was Pinfari's Big Apple MB28, production of which began in the late 1970s. Most Wacky Worm coasters produced by other companies have the same dimensions as the Big Apple MB28.


The Wacky Worm is the smallest "stacked figure eight" roller coaster, with the Tropical Track being slightly larger and the Zyklon being the largest. It has a figure-eight layout and a single drop, which in most cases has a trim brake.

Almost all Wacky Worm coasters use a standard sit-down train which runs above the track. Exceptions include Miami Dolphins, an inverted coaster from Fabbri, and Spinning Brucomela, a product from DAL Amusement Rides Company with spinning cars.
