Fossil Fighters for Nintendo DS.  Game only.  Has been tested.
 
Collect over 100 dinosaur-inspired creatures called "vivosaurs" and prepare them for battle in Fossil Fighters for DS. Use the handheld's touch-screen interface to hammer, chip, drill, and sweep away rocks to unearth an assortment of delicate fossils. The more careful you are with the fossil cleaning process, the more powerful the resulting creature will become in battle. Assemble individual body parts to build a fearsome fighter to challenge other vivosaurs. After each one-on-one fight, your vivosaur will earn experience and grow stronger over time. Use the system's wireless function to trade fossils or challenge your friends to creature-on-creature combat.
