Humming Top

The Humming-Top is a move used by Sonic the Hedgehog which debuted in Sonic Advance 2 and was later carried onto its sequel, Sonic Advance 3 and later on Sonic Rush and its sequel Sonic Rush Adventure. It is used in mid-air when launched into the air by gimmicks such as a spring. In the Sonic Rush series, it is the equivalent of Blaze's Jump Step.

Sonic Advance 2
First appearing in Sonic Advance 2, the Humming-Top serves as his side trick (executed by pressing the R button while holding left or right on the d-pad). Sonic kicks out his legs while they spin around in a blue aura which can destroy enemy robots that Sonic collides into.

Sonic Advance 3
The Humming-Top appeared in this sequel although the move can only be performed while Sonic is partnered with Miles "Tails" Prower. This time though and for later games, the player only needs to press the R button as Sonic no longer has a "neutral" trick (In Sonic Advance 2, neutral tricks are performed by pressing the R button without moving the d-pad onto a direction.) The aura for Sonic's spinning legs in this game appears to be white instead of blue.
