As with previous Warp Cannons, short coin trails indicate that you should perform a short jump, and long coin trails indicate longer jumps. However not all jumps are marked with coin trails, so it’s important to stay alert.
This course involves some fairly tricky jumps. You must not only slip through some very tight spaces, you must make sure you’re in exactly the right place when a flock of Crows locks on to you.
There’s a Red Ring floating above the coins at Point 3. To reach it, you must hop up while you dash through the area.
As usual, collecting the red coins requires that you make some significantly more complicated jumps. If you manage to grab them all, you’ll be rewarded with a Gold Flower.
If you haven’t already unlocked Flower World, simply reach the end of the level to do so.
