OK, basically, you have to push the middle button when the screen says "PUSH!" Then, when the power bar gets high, you push the middle button again and wait for one of the characters on the screen to fall over. BTW, the A button is the one on the left, B is in the middle, and C is on the right. Any questions?
O.K then, the bump game has 2 stratagies. You need to be fat to win. If your really skinny you won't go past the first round. If your 50 pounds you should do good. Now when your tamagotchis are back to back to eachother and the top of the says Push, press the B button and a power meter will show up. Try to get as much power as you can.
