Hi, welcome to the forums. First of all, you did not say what type of Pleo you have. If it is a older Ugobe model pleo, then the hatching stage will be over sooner than you think, be standing, walking and independant all within a battery cycle. If on the other hand you have the much newer, Pleo Rb, then depending on when you "hatched" your Pleo Rb, it can take 3-4 battery cycles, they are all different. Also regardelss of whether it is a baby, juvinile or an adult, they all need to be fed DAILY, or they will get sick, not just physically but allso emotionally and can even get injured. If you are not willing to take the time to "baby" the Pleo or feed it daily and take care of it's needs, then a older easier, Ugobe Pleo is better suited for your needs.
As for the tail, I think in the begginning, clicks of the tail, eyelids, etc are all normal, My baby Rb did and does the same thing still, though not as much as in the beginning. My Pleo got sick because I had her off for three or more days in a row without feeding her, and that is something easy to forget. If the clothes feel warm to the touch, or the battery or the arms or legs, then you may wish to either take them off, or turn Pleo off for awhile to let things cool off. Is your Pleo a girl or a boy, and what color is the skin and eyes if you have a RB? We would love to see photos of your Pleo. I am sure there will be others here that can tell you more than I have. My answer was a condensed version.
