For once, the heroes have a chance to relax and enjoy a nice quiet picnic together... yeah right! Things go from picnic when Chuck Thorndyke spots a meteor hurtling toward each- and its has a Chaos Emerald embedded inside! Now the heroes must travel to the South Pole and keep Doctor Eggman from getting his hands on it. To make things more interesting, the heroes decided to make a competition and split into teams from the South Pole to Station Square, passing through Argentina and Brazil. Sonic the Hedgehog and his friends compete against each others and Dr. Eggman (being the prize for the place in the competition) and the Chaos Emerald.
