Differences between beta and final
- In the Beta, this zone is referred to as Neo Green Hill Zone (not to be confused with the Sonic Advance level of the same name.)
- There are no enemies except the arrow-shooting totems.
- The layout is half-completed.
- There is a weird splashing animation consisting of misaligned bubbles instead of a splashing sprite. Tails has no splashing effects.
