The Bonus World is a secret area in Ty the Tasmanian Tiger.
The Bonus World is an area that is set at night and can only be accessed by getting 100% completion. That involves you collecting all Opals, Talismans, Bilbies, Golden Cogs, Thunder Eggs and Rainbow Scales, but you don't have to collect every Picture Frame, but that's because the rest of them ARE IN the Bonus World! There are 123 Picture Frames in the Bonus World. Some require you to hit buttons, activating a generator, and breaking invisible crates.
