This teeny-tiny article needs some work. You can help Sonic Retro by expanding it.

Egg Utopia
Seventh Zone, Sonic Advance 2
Number of Acts: 3
Level themes: Death Egg, industrial
Boss: Egg Frog

Egg Utopia is the last 2-act stage in Sonic Advance 2. It resembles Sonic 2's Death Egg slightly in appearance on the outside (as the background space suggests that the Utopia is moving at fast speed too), though the inside is where the similarities point the Flying Battery Zone of Sonic 3 & Knuckles. The gravity will change every once in a while, much like in S3K's Death Egg, providing a real challenge. The boss is a large Frog-like mech that also involves gravity switching.
