Sony's monkey-like mascot goes portable to let gamers take their imaginary friend wherever they go in EyePet for the PSP. Similar to earlier virtual pet games, such as Sega's Seaman or the DS' Nintendogs, EyePet presents opportunities to feed, clean, train, and bond with the creature, and through the PSP Camera the game offers unprecedented possibilities for hands-on interaction. The virtual pet can play with real-world objects it sees in the room, and players can stroke, scratch, tickle, or poke the creature by wiggling their fingers in view of the camera.
With simple hand commands, the EyePet can be encouraged to run and jump about. Gamers can also create virtual objects for the pet to play with in the game, such as toys or miniature vehicles, by drawing them on a sheet of paper and then holding them up for the camera to view. Other onscreen-only objects can also be called up and used to care for the EyePet, such as a handheld shower for bathing, and a dish and food container for feeding. As the creature develops, players gain access to new outfits and hairstyles for it to wear.
