Behold the Cracker Launcher screenshot, the one where Mario shoots from its barrel. What food do you see on the screenshot. Nothing? Really? Look at Mario's left, the food which is a little different colored than the others. It kind of looks like an egg. Yes, the egg marks the secret. It lies directly above a random bush. But there's something Sakurai didn't show you. In actuality the random bush wasn't a bush at all. The bush was a rabbit. Of course Nintendo didn't allow Sakurai the bush to be modeled as a rabbit so he modeled it as a bush but left clues. Look closely.
Look closelier.
Look more closelier.
With Photoshop technology we can look beneath the layers, the way Sakurai originally modeled it.
That is the random bush.
