We have these uber-cool space-girl dolls, but cannot discover their names or if there are more to the series. They appear to have been made by Irwin in 2002.
They talk and have some awareness of their body positioning, complaining of boredom when they're sitting or lying down. They each have a plug-in pet. The one on the left is clever and has an alligator/keyboard colleague. The other is daft and just wants to go shopping. She has a cat, but we're missing that. If you plug in the wrong cord, they tell you, ie: That's not Nizu!
If you know anything about them, please, do tell.
