Three Hedgehogs In A Mansion

Silver The Hedgehog stays with fellow hedgehogs Sonic and Shadow at the completely overused Super Smash Bros Mansion to get things off his mind. Little does he know that strange things occur at this particular mansion of super smashing brothers... possible Sonadow, Sonilver, Shadilver, Sonadilver. And yes, poor R.O.B. gets involved, mostly to help Silver out in awkward situations.
