SEGA upgraded Sonic's palette this week with two new wisps for Sonic Colours: pink and green, letting Sonic defy gravity.
The two additions were confirmed earlier this week as the "Green hover" and "Pink Spike" powers.
The first, green wisp, when absorbed lets Sonic soar to the skies, glide about and uncover much higher areas than normal. The other, pink wisp, is exclusive to the Wii version and lets our hedgehog friend cling to walls and ceilings with far more advanced spikes.
