I could never get Mario as my MVP....well, the second time I got Mario/Peach, an equal MVP.
Anyways, when you beat the game the opening backround turns brownish right? And then a red yoshi egg appears on the hill.
After obtaining all 40 yoshi eggs, PERFECT flashes accross the screen and the egg hatches, revealing a red yoshi instead of the egg. That's it. Finished.
No secrets, no playing as yoshi, no nothing.
I was very dissapointed.
