Major word of warning on Zombie event. The Zombie bosses need 11 x 3 zaps to defeat - so obviously you have to wait around for your energy to restore before defeating one.

DON'T GO TO FRIENDS ISLANDS OR TO THE OTHER HALF OF THE ISLAND while in the process of defeating one.

Your progress in defeating the Zombie boss will be forgotton, and you'll basically lose all the energy you've invested in it. I had done 9 out of 11 (i.e. 27 zaps) and made that mistake - when I returned to the first half of the island, the Zombie boss had vanished.
