Get every star coin in every level you play except for 2 star coins which adds up to 37. I practiced on world 1, and I skipped 1-4 #2/3 because I didn't want an ice flower. Also, 1-5 #2 and 1-Castle #3 are slowish. One idea for one we skip is 3-1 #2.

Route: 1-1 1-2 1-3 Star House: Use if you're like me and want to have a star in 2-3. 1-Tower 1-4 Goombaless Manipulation: https://pastebin.com/Erp4vD6s 1-5: Play this instead of 1-6 because you need to beat the level for a hint movie. 1-Castle 2-1 2-3 2-Tower 2-4 Secret 2-Castle 3-1: Also required for a hint movie. Watch those hint movies!

Notes: Any time a movie requires a certain number of star coins to show up, you have to beat its respective level. We skip a movie that only requires 25 star coins to show up in 2-6 because it costs 10 star coins to purchase.
