These items are also on display at the Auction Display Room (Towncenter -> Auction hall -> through the green gate). If you have any questions, please reply to this thread. Usually, we try to squeeze in some information and answers at the last moment, when everyone's already bidding on the item. But now that it's posted in advance, we can figure all this out in a much more relaxing way

There's also a "mongbat on perch" on my todo list since the previous auction, if I manage to code it it will also be added.
The auction 1 week later is likely to take place as well (not yet confirmed, i'd say 80% likely). The next auction will have a water house, an ancient yumi... and I'm thinking it might be about time for another Instanced Housing Land (so far we've sold 2, there's some coding that needs to be done before I can safely make more).
