The new GigaPets can do a lot of things. You can bring them outside and dig for treasure. (food, money which is considered bucks, kindness, cuteness, smartness, and mischievious points.) You can take it to the stores to buy necessary items for your pet.
You can unlock secret areas by going out the back doors of the shops. New places give you new items. Some places are special for certain items.
Go to the wishing well and you can get stuff there. Go to a fortune teller, go to the genie, and go to the new "Pet School" area.
Pet School is open from 7am to 5pm. Put your pet in school and you won't have to worry about its needs.
Halos indicate kindness or well behaved pets. More halos means you have a well behaved pet. Pichforks indicate mischievious behavior. More pitchforks means you have a badly behaving pet. Stars indicate cuteness. More stars means have a better looking pet. Lightbulbs indicate smartness. More lightbulbs means you have a smart pet.
You can sell items in the shops and earn lots of bucks for selling special items. If you dig in just the right spot, you may find an easter egg. If you choose to open it, you will receive a special item.
To connect your pet to the TV you need the game. It comes with the Hamster GigaPet. Put your pet into the correct place on the game and it will be connected to the TV. You can play games and go on quests and meet new pets. Whatever you receive on your TV will be automatically transfered to your handheld game.
Hope this gives you a better understanding of GigaPets.
