Ever try to keep the oddball from your opponents well on Colossos thats possible. After you grab the oddball above the the jumpy thing hop down to it DON'T GO IN IT instead face it and press right trigger it will launch the skull ball thing in to it. Doing this makes grabbing the ball impossible and you have to wait till it respawns. This is great if your enemies are trying to kill you launch it and intersept it at the spawn point.
