Yoshi Challenge & Finding Yoshi Eggs
After defeating Wart in World 7-2, you unlock a special Yoshi Challenge game on that file. It allows you to replay any stage in search of two Yoshi Eggs. Unfortunately, it gives no description of the kinds of areas the eggs could be hidden. The eggs are hidden in Subspace, but the searching for the egg is the challenge. Also, if you lose a life, you lose all of your eggs as well.
Yoshi on the Title Screen
To get Yoshi on the title screen, beat the game on Yoshi's challenge and instead of an egg,there will be a Yoshi.
