make sure the toy is not a 'named' character as it will likely just get nicked - i would also suggest a charity shop find as someone may just give it to someone as a gift if its new, or even just keep it for their kids.
actually the charity shop thing sounds quite fitting. it could be his first adventure - the escape from the charity shop!! lol
also many things would be an adventure to a toy - a day at the office, a trip on a bus, a pub beer garden, a school day, etc so although trips abroad etc would be cool, so would any response really
i want to do this now!
