I love them too! I've already picked up three kids' books and $50 worth of manga. Didn't find Gyobumungo, but I stumbled on the one fragilistikal was talking about and another little shop in the underground shopping area near my metro station. I still have several books from a few series left to collect, but it's going to be expensive to ship home the ones I have now. What to do!?

Also, any series you recommend?
