Family Room or Wild Animal Battle Field?

The boys have recently taken an interest in wild animals.  And you can't have wild animals without a battle.  It started with dinosaurs and has evolved, no pun intended, into large cats, bears, wolves and so on.  They set them up by category, I figure they are developing their organizational skills, be still my heart, all around the room and have battles.  They set up bombs and traps and it is really quite imaginative and fun to watch.  You have to look out though if you step on a bomb, like I often do while walking through the house, you will end up dead.
