Ghost Rings in Shadow the Hedgehog
Enables Light Speed Dash, even after rings have been collected
Grey, transparent Rings which appear after former Rings have been collected
Ghost Rings are transparent, unnamed rings in Shadow the Hedgehog.
The rings appear at a few lines of rings were the Light Speed Dash is and is the only method of traveling forward to complete the level. Unlike normal rings, you don't get any new rings for passing through them and are only used to proceed if you accidentally grab the rings instead of using the Light Speed Dash.
