Just for Fun
From PinataIsland.info, the Viva Piñata wiki
Designed for kids and first time visitors to Piñata Island, Just for Fun mode allows players to jump into a garden and interact with the inhabitants of this unique piñata world. With the level of difficulty turned down, sour piñatas stay away, resident piñatas remain healthy, weeds don’t plague your garden and you have an infinite chocolate coin bank account, allowing you to turn your garden into a veritable utopia of colorful creatures, garden ornaments and unique play areas such as the retro 70’s lighted disco floor.
