Blowing Up
Put the camera real close to the clock until the bird (that appears when you hit the [A] button) starts hitting/cracking the screen. Let it hit for awhile then it will blow. The bird will be black afterwards and will not blow up until you restart it.
To blow up the globe keep hitting the [A] button to shoot Earth until it explodes. It will say "Take care of our planet." But unfortunately you will lose the globe and have to buy it again.
