Anyway, today I got a letter from SimplyFun stating that they had tested the pieces in Ribbit (which were made in China) and that we should set them down and back away slowly. Lead in the paint.
I've got no beef with SimplyFun, which offered a full refund (or replacement toads, presumably safe to lick to my heart's content). But no way was I going to pass a chance to post using this title.
Anyway, given the number of games made in China these days, you should probably keep the game-licking to a minimum.
Update: SimplyFun's note about the recall.
