Piñata Paperchase
From PinataIsland.info, the Viva Piñata wiki
Trouble in Paradise
In the Pinata Paperchase (a mini-game within Viva Piñata: Trouble in Paradise) a pinata can race against three other pinatas across a course strewn with water, grass, snow and sand to see which can pick the fastest route to the finish line.
Piñatas will be faster or slower on certain terrain, i.e. lickatoads are fast in water but slow on sand.
There are boxes to smash open to pick up loathers that you can shoot forward or backwards or simply use as a rear guard.
