So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?
To do:
  • Quite a few unused animations for Sonic in Sonic World, including some from Sonic 3D's special stages.
  • Sonic 2 mistakenly uses Sonic 1's invincibility theme, but the correct one is still on the disc (as a 3-part AIF file).

Sonic Jam is a compilation of the four Genesis Sonic titles (Sonic 1, Sonic 2, Sonic 3, and Sonic & Knuckles) plus bonus content in the form of Sonic World (the precursor to Sonic Adventure) and a number of different gameplay options.

Isolated Sidewalk

Please elaborate.
Having more detail is always a good thing.
Specifically: How do you "glitch through the wall", and why isn't it on a Bugs page yet?


Behind the waterfall of Sonic World is a piece of sidewalk that can be seen by fiddling with the camera. It's possible to glitch through the wall via jumping through the waterfall by a certain angle, but why is it there...?

Unused Animations

To do:
Any way to enable these with hacking or cheat device codes?

Sonic World is actually based on an early prototype of Sonic Adventure! Sonic Team didn't want to waste the work they did when the game was moved from the Saturn to the Dreamcast, so they just put what they'd finished in Sonic Jam as a bonus for players. So it's no surprise that Sonic Jam's code contains unused animations reflecting the same animations used for Sonic in Sonic Adventure.

Unused Music & Sound Effects

A short, repetitive music loop.

Some kind of honking sound effect.

Unused Objects

The Sonic World engine has a number of unused objects, most of which are null. However, two of them still somewhat function and have models.



A monkey that walks in place. You can walk through it and he does nothing else. Probably meant to be in a tree.



A seagull that just sits in place. Probably meant to be in the sky. You can walk through it too.
