Spindash up a slippery cliff

'Super dash time!' he yelled. I t was a risk, but he lived for risks. Sometimes. In one smooth movement Sonic spun his body into a smooth circle, whizzing around like a blue Catherine wheel.

He flew through the air, bounced once on the cold stone floor and rolled to a stop at Tails's feet at the end of the cave.
