The Challenge
The Challenge is a level made by Glubfub, the keeper of the Vault of Secrets. To unlock his level, you must
enter "the challenge" into the textbox above him. After doing so, Glubfub will respond "My level? You want to try it?!" Then, a button appears above the wooden door with "The Challenge" written above it. He also tells you that you need 200 diamonds to unlock The Challenge.
