Sleeping Egg Zone

Sleeping Egg Zone is the third level of Sonic Chaos for the Sega Game Gear / Sega Master System, coming after Gigalopolis and preceeding Mecha Green Hill Zone. In keeping with the other stages of this game, Sleeping Egg consists of two standard Acts followed by a shorter, third Act which contains the boss. Geographically, this Zone is located on South Island.

Sleeping Egg Zone is an unusual stage with many breakable blocks, and numerous foreground walls emblazoned with Robotnik's image (as in Crystal Egg Zone for Sonic the Hedgehog 2 (8-bit)). There are industrial-strength pogo springs scattered throughout the level, which our heroes can use for bouncing up to otherwise inaccessible areas.

The greatest danger in Sleeping Egg Zone comes not from the badniks or other hazards, but rather falling off the screen in one of the many yawning, bottomless voids that litter the stage. It seems the best way to classify Sleeping Egg is as some sort of high-altitude construction site of Eggman's; as some of the level appears incomplete, with metal frameworks and half-finished blocky walls.

Boss
Throughout Sonic Chaos, and in a marked change of his tactics from other early games, our old friend Doctor Robotnik apparently thinks he's too important to face Sonic or Tails personally (until the last boss). Instead the Doctor deploys larger, tougher, nastier badniks as boss robots.

Sleeping Egg Zone's boss is (in keeping with the pogo spring theme of the level) a bouncing, gun-toting, Eggman-look-a-like robot. This machine can actually provide some problems, as only the head is vulnerable, and the speed of its bouncing is such that landing a strike takes some work. All the while, the boss' Vulcan cannon spits bullets in Sonic or Tails's direction.
