Extra Coins with Yoshi Trick
This trick allows you to make new coins appear using Yoshi. You can use the extra coins to get to one hundred coins faster, or to increase your coin record on a particular level. This trick is fairly simple to do. Start off by choosing Yoshi and entering any level. Go up to an enemy, and swallow it. When you swallow the enemy, press R to turn it into an egg. Then, find another enemy, preferably one that is near several other enemies. Aim so that your egg will not directly hit the enemy, but will ricochet off of the enemy. Shoot the egg. The egg will hit the enemy and then bounce of. Since the game thinks that the egg exploded, it will place the enemy coins at the place where the egg hit the enemy. It will also give you the coins for the enemy if you defeated it. Since the egg was not destroyed, however, it will continue to go and hit another enemy. When it hits the other enemy you will receive coins for defeating the enemy, and you will receive the enemy coins from the egg again! If the egg bounces off several enemies before it breaks, you will receive coins multiple times for the enemy that was in the egg. The more times the egg bounces off enemies, the more coins you get. This is especially useful when you swallow enemies that give you blue coins, since you can get many blue coins by using this trick. This trick is difficult to pull off on regular enemies, but it is worth it. This trick is easiest to use if you shoot the egg at a Bob-omb since they are small and usually do not break the egg.
