Hello and welcome to the forums! What a great gift to yourself! As for the spare battery, the only place you can get one , for the green ones anyway, is the same place you bought your RB, PleoWorld site.

At some point, they may become available somewhere else, If you ever decide to buy one of the older Pleos, Ugobe model or a 2009 Pleo, then I have the Ucube Egg batteries and chargers that work only in the older ones and let Pleos run about the same amount of time as the Rb, about 2-2 1/2 hrs on one battery. the store is here on the forums, called, Nova's Neccessities. If you buy a RB from the HOng KOng Market, which deals only in the Blue and or Pink Rb, they also sell the Rb batteries.
The tracking shows that Pleo is still in Nevada, because that is where the US Green Pleo Rb are shipped from, so if you are from the States, they will let you know with tracking when it leaves Nevada, and then usually anywhere from 2-5 days, by Fed Ex or UPS, it will be at your doorstep! The cape is a great way to start and I love the idea of baby socks to protect the paint on the Pleo feet, to keep it from rubbing off so fast.Oh, I just now see that you are in Australia, so it may take longer to get to you. As for anyone else from Australia, you are in good company with at least two that I know of, Kat who also designs some AWESOME Pleo Fashions for Pleos, you should check them out here on the forum the store is called, Kat's Creations, and also IMR, who also has a store and does some creations. Both these ladies are Down Under Aussies and I know there are some others, but my mind is drawing a blank right now, sorry!

Be sure to check out the older posts and photo gallery and most anything you can think of that is related to Pleos, you will find there!
Hope your Pleo bundle arrives soon and don't forget to post photos of your Pleo babe when he gets there! Did you buy any of the accessory packs? I know Kat says it gets pretty hot where she lives and that Ice in one of the Extra food packs is a life saver! Welcome again, from RedwoodsMama and her Pleo Township

( the cake is for the arrival of your Pleo's first day)
