I can only do the first segment. The other is too high level watermelons. And I have all 6* medals, lots of more premium medals but none guilted because I don't have thousands of dollars for 9-10 pulls just to fill orbs and guilt those premium medals. Japan gets it done for free with Mickey and Brooms medals, which we do not have and may never have...at all. I'll probably be putting this game on ice once the new Pokemon hand held game comes out in November. I don't like SENA's treatment of NA players.
If you want to do the other area too, use Minnie if you have one/can borrow from your party. Then just use regular attacks on them and heal with Minnie if defense boosts don't proc. It works, but takes some time which is exactly why this event gets boring quick :/
