Logan and Connor's current craze is to fight monsters. They have two toy laser swords and this is currently their weapon of choice for their beastly fight.
Usually, the monster is hiding in the kitchen. Logan will go in there first with his laser sword and come back to the living room. The monster will then usually end up in the living room where both boys will fight it with their swords. The most common outcome is the monster being transformed into an ant by Logan or being held prisoner within Connor's sword... ;)
