Flipper

Flippers (フリッパー), also known as Pinball Flippers, are reoccurring pinball gimmicks in the Sonic the Hedgehog series. They are neon colored levers, which are usually hovering in the mid-air or are set on pinball tables along with many other pinball-related objects and gimmicks. Flippers are first introduced in 8-bit version of Sonic the Hedgehog and since they have been featured in Casino-themed Zones or Bonus Stages in each game where they are seen.

Description

When the playable character lands on a flipper, he/she instantly curls into a rolling ball.

Trivia

 * Flippers in Sonic CD were mute until the 2011 re-release added sound effect when it launches Sonic to the air.
 * The neon red and white colored flippers in Nintendo 3DS version of Sonic Generations misleadingly recycle the Bumper sound effect when the player gets launched backwards, while the Bumpers themselves have a different sound in the game.
