LEGO Racers Xalax

I was on the LEGO wiki for whatever reason, and I got to the LEGO Racers Xalax sets. They're basically little cars that have a blobby guy and you race him. These scare me.

I have one from when I was a kid, a little blue guy named Shredd.

There's another guy; a little purple guy, named, well, Gear.

There's a green guy named Snake, which is two letters off from another green guy.

The yellow guy is named Pulse, and our own yellow guy has a pulse.
