:V From the thumbnail I couldn't tell that you drew the entire walker so I thought "Tee hee that's a neat idea." Then I saw that you drew the entire thing and was like ":V V: oh hey that's like 3x as awesome suddenly."
tl;dr this is awesome
(and I managed to -forget- to name my person "Raptorbane")
It's the Pokewalker. It basically counts your steps and you get points to spend on finding items and catching other pokemon. It comes with the two new pokemon games and can connect with them. Basically it's a way to get extra items and pokemon in the game.
