An interesting thing I noticed a long time ago was that a baby was asking to be adopted, and when a girl agreed, the baby was acting happy, until he asked the girl to take him to her guild house. As soon as she said she didn't have one, the baby returned right back to the "adopt me" act and completely ignored the girl as if they had never met before.

As an experiment, I "adopted" some of there players, but hid inside a bush at the time they were warped into my guild house. 90% of the babies, upon entry, would go straight for the gralats in my farm (and then realise they were all locked and then leave and go back the the "adopt me" phase).
