Welcome and be forewarned as Crewella stated, you may find yourself under the spell of Pleo , just one gaze in his/her eyes and heard that little coo sound, and I felt myself melting like butter.

It is compareable as a feeling when you hold a soft little baby kitten or have a baby puppy lick your face, ( but without allergens from Cat Saliva ( if you are allergic, mind you I love cats, I have nine myself

) or without the doggy odor, though puppies somehow for a certain period, are lucky and smell like PUPPIES!) anyway, be warned, you could get hooked easily,
I bought my first Pleo for a Christmas present last year, and once I turned her on,( wanting to check out if she was going to be a worthy present as I knew ZERO about Pleos and stumbled upon them by accident, just looking for Dinosaurs ) I was Hooked, line and sinker Hooked! Not just was Pleo cute and so Unique like Nothing I had seen or heard of before, but I soon learned by observation and by reading and doing research here on the forums, that Pleo was not the appropriate present for my grandson, The box says children 8 Years and +, and that is just a generalization. I think it totally depends on the child or individual. My grandson was 8 Last year, but Pleo is not a remote controlled beast that you can make do anything...( that is one of the points most of us find charming I think.)
My grandson was more suited to D-Rex, the big Remote Controlled dinosaur that was a hot seller last year, and so to make a longer story shorter, I bought my grandson D-Rex and he is thrilled with it, and I fell in love with my Pleo, who is now Nova.
Nova does not stop there, or I should say Pleos don't end there I needed companions for Nova and now my house is filled with Little green babies who also get along well with my nine cats and one dog.

I would say read up on as much as you can before you wrap Pleo up for Christmas so you know as much as possible and be sure to ask questions. If it is a Ugobe model Pleo, then you are probably looking at a battery/ batteries that have been sitting for quite some time and are not going to work for very long. You can either buy the reconditioning charger with the switch Crewella told you about or buy a new battery from Pleoworld, or perhaps check out my store here on the forums, Nova"s Necessities, where I sell both kinds of batteries, and I allso ship worldwide, at very cheap prices. I have sold to lots of people here on the forums and you can either P.M. me and I can tell you how to get the type of battery you want.
There are other nice items you may want to check out for your ( children's ) Pleo here at this site or as well as PleoWorld or on some of the auction sites, clothes, etc. Pleo can be reset like Crewella said, so Pleo can be born all over again, Just be aware that all previous memories etc., that Pleo has will be erased, and Pleo starts all over again as a baby.I do not know anything about generic adapters,etc, so others will possibly be able to tell you more about that. One person who can be of big help and answer questions about skits,etc, is IMR,( InMemoryofRomeo ) Actually there are a lot of knowledgeable people here who can tell you a lot regarding more technical questions that I can not answer.
Good Luck with your Pleo (children's )
