Seaside Hill

This is a sub-page of Sonic Generations (PlayStation 3, Xbox 360, Windows)/Challenge Act Content/Unused Object Layouts.

Act 2#

Image	Challenge Act	Description
	Trick Island Surf, Sea, and Sand	A set of four dash panels can be found on the sand before the turtles.
	Rouge: The Temptress Trick Island Terror of the Deep	The cart only spawns in Terror of the Deep, but can also be found in "Trick Island" and "Rouge the Temptress" when viewing them in a level editor. Spawning the player to it will disappear. It's also worth noting that the object is placed backwards for some reason.

Hi-Speed Hijinx#

A singular spike set is found inside the walls underwater. Nothing much can be said out of it other than just being a misplaced object.

Underwater Challenge#

A few rings at the beginning of the stage, and more rings plus a dash panel at the rolling rock section, can all be found leftover from the original level.

Rouge: The Temptress#

Image	Description
	Some extra platforms can be found under the turtle on the right pathway area.
	Two sets of jump panels and iron balls can be found above the playing area, where the cart track would be.
	The other entrance above the Goal Ring has a dash panel leftover from the original stage, as it is angled for when if it were on a loop.

Trick Island#

This challenge act has the most misplaced objects compared to the rest for this stage.

Early Red Star Ring Placement#

Interestingly, when browsing the stage through a level editor, this stage contains a singular red star ring leftover from the game's development. The item is placed at the rail tunnel area, with possibly the only difference of it being slightly higher and not on the rail compared to the final.

Challenge Act	Main Stage

Other Misplaced Objects#

Image	Description
	A set of five rings can be found under the first loop where the cannon shortcut would be.
	A singular checkpoint, before the rainbow rings and orcas, can be found leftover from the original stage.
	Two sets of light dash rings can be found below the pathway, just after the checkpoint above. It's unknown if there was a light dash section planned or a slight mistake.
	A set of four wooden crates can be found under the bottom tunnel area (just before where the cannon and turtles would be).
	Two sets of dash panels can be found just past the wall of the previous area said above. One of these sets can also be found in "Surf, Sea, and Sand".
	A singular rail dash panel can be found leftover from the main stage.

Surf, Sea, and Sand#

Misplaced Platforms#

Just like with "Rouge: The Temptress", there are some more platforms that can be found under of the turtles.

Leftover Objects#

A few rail dash panels, rings (at the final section where the rocks would be), and a singular door on the bottom path of the palace can all be found just outside the playing area.
