The unused Stadium level.
How to find the secret "stadium" test level in Scribblenauts Unlimited
How to access the Stadium using Cheat Engine.
The Stadium is an unused level in Scribblenauts Unlimited which exists in an unfinished state. It was used as a test level by the developers. This level can only be seen without hacking by using the "--autoloader" command line parameter in the PC version, and even then it only appears for a brief period of time and cannot be interacted with in any way. It is, however, possible to access this level through memory hacking.
