The 100-ring bonus is one of the oldest traditions in the Sonic the Hedgehog series, dating back to the 1991 original, where gathering a hundred rings granted an extra life with a triumphant jingle. Security Hall is Rouge the Bat's treasure-hunting stage in Sonic Adventure 2, released by Sega in 2001, and its ring-collecting gameplay made the chime a constant companion for players. Clips of the jingle later spread through gameplay compilations and retro gaming memes, where it became shorthand for any hard-earned in-game achievement.
