Pokémon Ranger: Guardian Signs - Nintendo DS

In the region of Oblivia, a gang of thieves known as the "Pokémon Pinchers" are stealing wild Pokémon and planning to use them for their own nefarious purposes. Two Pokémon Rangers, Summer and Ben, are sent to investigate. However, after an encounter with the Pinchers, one of them is kidnapped while the other is left stranded on an island. There they meet a Pichu with a ukulele, who teams up with them to help rescue its Pichu friends who have also been captured by then Pinchers. Can you rescue your partner, and save the Pokémon of the Oblivia region?

Pokémon Ranger: Guardian Signs is the third in the Pokémon Ranger series. As with the previous games, you move your character around using a device known as the stylus, as well as battling with a device called the "capture styler" (represented by the stylus). To battle, you encounter a Pokémon on the touch screen, and your aim is to repeatedly draw connecting loops around it until you deplete its health to zero, allowing it to join your team. Pokémon can be used in the environment to clear obstacles and help you progress (such as such as cutting trees, extinguishing fires and so on), or by assisting you in battle and helping you weaken enemy Pokémon. Near the start of the game, Ukulele Pichu becomes a part of your team and randomly appears during battles to assist. If you tap it when it appears, it will jump into battle and play its ukulele, which scatters musical notes around the screen which weaken enemies.
