Okay, I've finished upgrading all HaroHapi areat items to level 5. Now I just gotta grind for miracle crystals and get up to level 150 (that might take a while) then I'll have the HaroHapi lane design. Currently I have 298 miracle crystals, and I think I need 330.
Edit: Welp, just exchanged a bunch of michelle stickers for miracle crystals and now I have 338. I kinda don't want to waste all of them though.
Edit: Oh... Now I'm out of coins..................................................................................................
I'm also out of Michelle Stickers, but that's fine.
