This stage takes place deep within Dr. Eggman's pyramid base, which is filled with dangerous enemies that Rouge must defeat or avoid.
Level Up Item
The Pick Nails can be found in this stage. They are inside a room in the Egg Fish Chamber.
Collect 100 Rings
Rings are scarce in this stage, so the player must avoid taking any damage. To collect one hundred Rings as quickly as possible, the player should start by grabbing every one from the room the stage starts from. They should then take the exit beneath the giant scorpion statue and keep going straight until the Egg Snake Chamber is reached, picking up every Ring inside it. From there, they must turn left and head toward the Snake Altar room. Upon entering, they should break the Wooden Container to the left (next to the cagedHalf-Fish) to reveal a Super Ring with twenty Rings. If everything is grabbed from this room, it is possible to obtain one hundred Rings by gliding from the tops of the pillars or by collecting the Rings atop the large central platform.
Find the lost Chao
The player should first play the Mystic Melody at the Ancient Ruin atop the large center platform in the Snake Altar room and jump into the Warp Hole that appears. The player will then be transported to a room with a giant Weight lying in the center and a Warp Wall on the left. They must dig into the Warp Wall, and they will enter a similar room with another Warp Wall in the shallow hole on the floor. The player must then break through the first Iron Container in the ground south of the far left corner and hit the exposed Switch, then dig into the Warp Wall in the floor to be transported to the previous room where the Weight is now suspended in midair. The lost Chao can be found underneath it.
Get the 3 Gate Keys in 3:00
Since this stage is relatively small and circular, the player should simply run around until something comes up on the radar. The points received from finishing early are substantial, so the player can use a Hint Box without noticeable consequences.
Clear Hard mode
The first key is in a Cage at the end of the boundary hallway between the Egg Scorpion Chamber and the Egg Fish Chamber (but closer to the latter section). The player should destroy the Cage by standing close to it so that the Kiki nearby will throw a bomb at it, or pick up a Kiki's bomb and throw it at the Cage themselves.
The second key is in the Snake Altar Room, inside the Warp Wall on the west side of the room. Unfortunately, a stack of Cages is blocking it. The player needs to smash the Wooden Container on top of the altar below the Warp Wall and the Iron Container in front of it before grabbing another Kiki bomb. Otherwise, it will not be possible to get back up here while carrying a bomb. Once the player has a bomb, they should use it to blow up the Cages, then climb up and dig into the scorpion's tail.
The third key is inside a Cage located in an upper alcove in the Egg Snake Chamber. The player should put the Treasure Scope on and grab a bomb any Kiki throws. They can then head towards the Egg Snake Chamber and hit the Spring that it is now visible via the Treasure Scope, before placing the bomb to destroy the Cage.
Chao Container locations
The player should play the Mystic Melody near the Ancient Ruin atop the large central platform in the Snake Altar room. The Warp Hole that appears will transport them to the first Chao Container's location.
The second Chao Container is in the first green room west of the Egg Snake Chamber.
The player should break the Wooden Container in the right corner (relative to the entrance) of the room where the Pick Nails were. Doing so will reveal the third Chao Container.
In the Snake Altar room, climb up to the top of one of the six highest pillars. From there, Big can be seen hanging onto a wall above the room, close to the picture of a flower.
In 2P Battle, there are no Egg Beetles. Both players will start in the Egg Fish Chamber. The room where the Pick Nails would have been in is accessible, and the path between the Egg Scorpion and Egg Snake Chambers is blocked off.
Egg Quarter's and Death Chamber's stage layout are almost the same; this is probably because Death Chamber is Knuckles' version of this stage, albeit without the robots searching for him.
