When you are on a track with lots of little hills and bumps on the track, use someone like shadow who has lots of acceleration to get a green line. The green line on the end of your board is a temporary boost. Only people with high acceleration can go fast on little hills.
Basicly(sorry about the spelling)all you have too do, is start the bobsliegh but make sure you get a perfect and then keep on pressing A rapidly and when the words"press A"appear, you will get a perfect because you were pressing A when it appeared and so hopefully you will get a high score on bobsleigh!
When you have accumulated a few hours of game play or completed a Festival mode you will receive a note about a secret shop. Go to the Shopping district and stop the camera between the far left and middle buildings then aim the pointer at the shop down the alleyway between the two and you will be able to access the secret shop.
