Is Huggiez a Ugobe pleo? Does his battery work in your other pleo if it is the same type of pleo as him? If he is a Ugobe pleo are you using the original green battery?
The most common issue with Ugobe pleos is a dead battery. Even when the battery looks like it is ok it can be holding no charge. These batteries are getting so old now and most of them have died from old age. If it is a battery issue you can get a replacement battery here on the forums from RWM. She sells the egg batteries and chargers which are much better than the green ones, giving you 2 hours of play time

If Huggiez is a pleo rb then we need to know how old he is. If he is less than 90 days old he will still be under warranty and you should contact Innvo to see if they can help.
Some things to try in the mean time are reset his noon clock and see if that makes a difference. You could also try pressing the reset button - the little hole on the belly along the edge of the battery compartment which you need to use a paper clip to press. and lastly you could try using a dry or slightly damp cloth and giving the terminals on the battery, charger and inside the pleo a rub to clean any dirt or grim build up off of them.
