Remember that part in Finding Nemo where Dory and Nemo's dad run into the shark meeting? The shark's are trying to give up eating other fish and their motto for the meeting is, "Fish are friends". (Yes, I'm going somewhere with this, kinda.)
For some reason, the child has decided that the Sellbot cogs are her friends. No amount of reason or discussion is helping with this odd fixation. Even though those cogs are just as happy as any other to steal her gags and send her back to the playground, she insists that they are her friends. (I know, the analogy would make more sense if it were the fish in Nemo having the meeting about the sharks, but my brain is fuzzy and that's what's sticking.)
Other than this little splash of weirdness, she continues to have a lot of fun playing ToonTown. She happily narrates what she's doing and regularly talks to the screen. There's definitely no need to wonder what she's thinking as she plays, since every thought comes out through her mouth.
I like how ToonTown really encourages the players to team up and work together to defeat the cogs. Yes, there's some competition in the mini games, but the overall theme of ToonTown seems to be teamwork. The child is currently playing Webkinz a lot too. It has some enjoyable parts, but is totally lacking any sense of working with others for a common good. I'm glad she still has ToonTown in her gaming life.
