There are no safespots during boss fight, but the best spot to be is at the center of the bottom of the screen. This is because the Cat will be protected by the Owl from the Green Stem Head in the center. Concentrate fire on King Shroom, while constantly adjusting both characters so that the Cat does not get hit. After King Shroom is defeated, focus on attacking the Green Stem Head that fires Bees. It is the next most dangerous opponent. After that, just finish off the other two Stem Heads.
