While I've only seen a handful of Xplorys in the wild here in the US, they're apparently keeping babies out of range of car exhaust and wheeling up to cafe tables all over Japan.
In the sidebar on the blog Shotaro with Xplory, Shotaro has gathered pictures of at least 28 other [your baby name here] with Xplorys, his Xplory Nakama* or "posse." It's good to be the king.
* This is distinct from the infamous Xplory Zoku, the gangs of infantile delinquents--or chinpira-- who hang out near the train station and terrorize passersby with their scary-loud noises. You know bosozoku? Same thing, but with strollers.
