N5 - The Tidal Coast: ★★★★★★★☆☆☆ This stage...I hate it. Probably the most difficult northern stage. It has PLENTY of troubles to go by with. Thankfully, it isn't too long. One thing to look out for is to not become Impact Wario in the beginning. Another thing to look out for is to make sure you grab the Gray Key and enter the room with the Green Key all in the same Spring Wario reaction.
