Early concepts of Dingodile had the character completely naked, with a black canine nose and being built more like an actual crocodile. Later concepts added clothes, such as dungarees, a shirt and a slouch hat.
Early designs show that Dr. N. Tropy's personal time machine was originally designed to look like a giant digital watch around his waist. Further designs changed the shape and added more gears, chronometers, pistons and exhausts. The digital clock face was eventually replaced with a traditional analogue face.
Toys for Tiny Tiger and Dingodile were created by Resaurus Toys, but were only seen at a convention. It's not known if they were from the unreleased series 3, or just scrapped figures from the previous series.
Doctor Nefarious Tropy was added to the game as the developers felt a time travelling boss was needed, as the game focused on time travel. His shortened name, N. Tropy, is a pun on entropy, a term used to measure randomness and disorder over time.
The twentieth level's name, "Tomb Wader", is play on the name of the Tomb Raider series.
