Barrel Cannon Canyon

Any% All Stages
Notes:
 * You have to do an extended roll to get through the entire line of four Kritters right after the halfway barrel. To time it easily, simply let go of Y after you roll into the second one and press and hold it again after you roll through the third.
 * Hold down B for a full jump after you land next to the barrel (after the extended roll) to make sure you get enough height to reach the next tree.

Notes:
 * There is no extendo through the group of three Kremlings.
 * You will need to move a little bit past the barrel before you land in it — as shown in the video — to spawn the barrels early and speed up the sequence.
