I like Doraemon too.
I was hoping that cartoon would reach the US. I heard it might be but that never happened. ^_^
I'm sure those are multi pets. If you really like Doraemon, I say get it! But don't expect it to be Doraemon. There is only one true Doraemon & Doraemae pet and that isn't it.
Speaking of which, the actual Doraemon pet is a total hoot! I highly recommend it.
The real one has a bell on it and is in the shape of his head.
