Art Description
Sonic3C0408 MD Sprite LRZ2DeathEgg.png
An earlier version of the Death Egg sprite seen at the end of Lava Reef Zone Act 2, found in the ROM padding area. It's using the colors of the enemy palette line ($01) and the shading differs in areas[1].

Sonic 3 ending leftovers

Big Arm cannot be fought in this prototype, but its data from Sonic the Hedgehog 3 remains intact and can be hacked back in to the game. Once restored, it can be fought and defeated as normal, and the ending from Sonic 3 will take place, followed by the credits. This time however, Knuckles can also get this ending, and uses all the correct poses until the giant Sonic sprite shows up, messing up Knuckles' palette. For some reason, the screen fades to the credits a slightly faster than it does for Sonic & Tails[2].
