I did it, i finally unlocked my first adventure mode seedium(not counting torchwood), the banana launcher, twas a bargin, only 2500 coins, 6, cycles, over the course of days.

Update on the Rented Adventure Mode Plant Seed Packet War (or RAMPSPW), Its a neck-to-neck brawl between Banana Launcher, and Moonflower, with only 10 seed packets to go, with guacodile only needing 14 left.
