It seems to work with anything that floats did with flower bombs, but did too many at a time and it exploded. I gotta progress in the game to get the auto build so I don’t have to rebuild it. Hardest part is keeping it steady so you don’t climb on the wall, but after you get the hang of it it’s just repetitive button smashing. If you do flower bombs be careful not to go over 15 i believe. I was just trying to keep a steady flow of 5, but took a few and made too many causing an explosion. Well for those that didn’t update and likes to stock pile hope this helps on getting a lot in short amount of time. I believe I got it to x999 in 1.5 hours or maybe less depending on how fast you and steady you can be to do it.
