Congratulations on your new Pleo! If you're going to use the original Pleo cape, you may want to remove the rubber bands on the legs and replace them with elastic or string. The capes from Innvo use very tight rubber bands that tend to damage the skin of the Pleo over time, so the cape actually ends up doing more harm than good. If you're at all handy at sewing, you can also use the original cape as a pattern to make new outfits with.
I would also recommend always putting your Pleo into the packing position when shutting it off. Storing Pleos in the curled up position actually damages the skin much worse than anything else, but if the Pleo is stored in a standing position with the head and tail stretched out straight, there should be very minimal wear to the rubber over time. If it's running on one of the newer operating systems, you can hold down the Pleo button to get it into packing position, otherwise you'll just have to wait until the Pleo is standing in a similar position to shut it off.
The skin will probably not stay perfectly pristine over time, especially given the age of Ugobe Pleos, but I would try to enjoy the Pleo without worrying too much about this. If it's stored properly and wearing a cape, the wear should be minor. In any case, good luck and I hope you have fun with your new Pleo! Do you have a name in mind?
