Ouch, that flinch really hurt. Okay, Nita, start off with a Venoshock at Munchlax, then Disable Camerupt's Rock Slide. Finish up with another Venoshock to Munchlax.
Kit, I think you should rightfully be asleep by now. Regardless, use Heal Pulse on Nita, then Confuse Ray on Munchlax, and then use Psychic on Camerupt. If you fall asleep, just skip the actions that you would have performed while asleep.
