Sonic the Hedgehog Bonus: Special Stage
The character of Sonic the Hedgehog came about after Sega launched a competition among its designers to come up with a new mascot. The character is a cross between Mickey Mouse and Felix the Cat, and was originally named ‘Mr. Needlemouse’.
To get to Sonic’s Special Stage you normally have to finish a level with more than 50 rings and then jump through the giant spinning ring that appears!
Sonic must then traverse a rotating maze to collect the Chaos Emerald at the center. Despite being a bonus stage, the Chaos Emeralds are a core part of the Sonic storyline.
There’s 6 the Chaos Emeralds to collect, one from each bonus stage, if Sonic gets all of them you’ll be rewarded with the ‘good’ ending cinematic, and Dr Robotnik will be defeated once and for all, well… until Sonic the Hedgehog 2 at least.
