Town Mission 17: The 100 Forgotten Rings

Town Mission 17: The 100 Forgotten Rings is the 17th mission in Sonic the Hedgehog 2006. It takes place in Sonic's story.

Guide
First, touch the first spring at the beginning. Scale the rooftops and make sure to grab each ring as you go (this can be difficult, as most roofs will force you to go in one direction). When you get to the end, you will only have 99 rings out of the 100 needed. Hit the blue exploding box behing the NPC who gave you the task, and a ring will drop (apparently out of the man's "pocket") for the player to grab. As soon as the player grabs the 100th ring, the mission will be completed.
