These are Ripcord Racer type figures. (Ripcord Racer is a term, like wind-up-toy, pull-back-n-go, etc, not the name of a line) The blue axe-shaped thing (meant to look like energy?) is the ripcord. There's Eggman in his Egg o Matic which will roll along the table, Sonic running in a 'swirl' which is launched from a handle & Knuckles on an Extreme Gear hover/rolling board. Each should be about 12.99 What size are they?

In the gallary is the MIB shot of Sonic Ripcord Wheel Launcher. You can see the little figure in there (dot says 'removable figure'), the silver colored launching handle thing & the other dot says "glowing wheel". Does it light up? Does it glow in the dark? The figure there is their 3 inch scale one, but the whole toy is 12.99 at Toys R Us.
