There's not a whole lot to discuss with this track. I think that it's a little bit more enjoyable than other racetracks in the game such as Mario Circuit and Luigi Circuit, with some added elements such as the chain chopper and the piranhas which add a little bit more dimension. I think there's an overall cheerful vibe to this track, with some perky music and cutesy design. That being said, I'd consider this track to be pretty inoffensive rather than exciting. It's a little bit sleepy and immemorable. It's definitely a filler track, but I wouldn't mind playing it so I think it serves this purpose quite well. Overall, I think there's no reason to dislike this track, but there are certainly more exciting ones in the game.

I actually agree that Dry Dry Ruins is better than the ones eliminated so far! My personal least favorite of the ones left is Mario Circuit 3 because that one took me the longest to be good at
