Managed to find everything except for 2 flowers.
EDIT:
Extra red coin in this stake.
Stats after first midring.
It's actually possible to pound down this stake from the side when the launcher is still on top of it, funnily enough.
Stats just before second mid-ring.
The ice melon here is really difficult to nab.
Stats at the end, completely missed two flowers somewhere. Collected 21 red coins due to the aforementioned extra at the beginning. No clue what I missed, unless both flowers are hidden in sand blocks.
