Earthquake and Tornadoes
While in the ranch, if you shake the wii remote, an earthquake will occur in the game causing all the pokemons on the ground and the miis to fall down. And if you zoom all the way out and shake the wii remote, instead of an earthquake, a tornado may occur causing the pokemons to be lifted off the ground and they spin around in circles until they fall back down.
Easy Pokemon
You can advance the system date to get more Pokemon easily. Start the game, leave, and save the game. Advance one day in the system settings, and enter the game again. You will get another Pokemon. You can set the clock back to the correct value afterwards. Although you will get a message about your game data being corrupted, you will still retain the new Pokemon. However, you will have to wait two days for your next "new" Pokemon, but the daily new Pokemon will appear after that on schedule.
