Grind the roller coaster around for awhile to get a lot of Stokens. Note: Make sure to not fall or get hit by the roller coaster train.

Skate over to the large roller coaster. Enter at the entrance of the roller coaster skating in the opposite direction of the cart. Fully skate the roller coaster jumping over the cart when it comes around and land at beginning of coaster entrance. Do not fall. Land it to get a few hundred Stokens.
