How to beat soul melter ex?

I am going to tell my own experience: First, I met with 3 Friends, because the CPU usually is not a good friend. First, my 3 friends selected the Fire sister, because of Whispy Woods (Magolor only using fire atack on that battle). After the whispy woods battle, the lodoaut is always the same: one friend with the Water sister, other with fire, and last with electric. Every time it charges, magolor should use the ship (with all player in), and the mage sisters the circle. The meals should go like these: every 2-4 battles, use a bad food or meduim food. It depends the time to eat them becuase the damage of a team (at least 2 players damaged), and the type of food depend the amount of damage (tangerine or coke). Use the tomatoes, one at the half of the challenge, and one two before the last battle.
