Don't have my ID on-hand, but you can check the Friends List topics for it. Have a fairly synergetic team of 6*s, one of which (Anemone) is totally maxed on ampies with 3 maxed-out equips and one (Bride Orchid) is about halfway to max on ampies. They tend to one-round the pests in this event (even bosses rarely last more than 2 rounds). Note that you'll want a girl at Evolved Max to get full statistical power out of them (and any other helper squad)
