I found new info from Blogagotchi about the Chu's...
"Well, I've decided to take a short break from my Oceans. Not for too long, as I still have some things I want to try out, but just for a little bit. I've decided to try this Tamago Chu pair. See what they are like. So far, when you pull the tab, you see tama planet, drooling and all! Then, you set the date and time (like all tams) and pick one of 3 characters to start with on each. You give the ones you choose names, and off you go! They appear on your screen from a space ship! A very cute touch! Right away, these 2 started doing things. The Boy started Fishing, while the girl was cooking. Talk about a steriotype! Anyways, these are very easy to connect. Just press them together and off they go! The little girl leans in with her cheek near the boy's side of the screen while he leans in and gives a kiss. I can see why this one is rated ages 15 and up! I'll post more as I know more. Really pretty cute so far!
I'm still running my Tamago Chu pair. They each had a little boy baby. I was trying to figure out what each button on the back did and accidentally reset them both. That's okay though because they had stopped doing new things. I did find out that you can name each baby as they come along. That's pretty cute!"http://www.blogagotchi.com/kyliesmum2/
