Note: This stage has some extra areas in Free Play, they also contain some Canisters, it's hard to visually depict this stage because there's so many areas. This stage will also require two playthroughs to get everything. At least three of the Canister are Free Play only.
You'll notice as you fly along that there's now a split in the path, taking the path that was blocked in Story gives a few more Canisters.
Canisters 1-10: All of them are sitting in the main path, all pretty easy to get as you fly through the stage normally.
Unlocked Character: Speeder Bike - Trooper (800)
