I'm stuck at a 9.5k that I just can't seem to get past. Mario Circuit 1 is at an 8.8k, and Dino Dino at 12k (GIANT BANANAS EVERYWHERE)Yeah, Cheep Cheep Lagoon is the worst with RNG because it determines whether or not you get 4 item boxes vs. 6 item boxes (+ some jump boosts).
I have no idea how I cracked 10k on that.
