First you must create a new garden and name it Pinata People, wait for it to load then save the game and exit back to the main menu.

The credits will now be unlocked.

To display the credits you must first smash a pinata, but before you smash the pinata destroy the debris around it.

By doing this you may have uncovered some accessories, if not keep trying, you will eventually uncover something.

To unlock the wishing well you must smash every pinata to reveal the entire credits.
