I have a ton of the old Giga pets that came out when the original tamas came out in '97. There was Compu Kitty, Digital Doggie, Microchimp, Komputer Koala, Floppy Frog, Virtual Alien, Bit Critter, and some promos. They were so much fun! You could teach your pet tricks. The new ones are a bit easier to play, because the older ones were pretty hard if you didn't know what you were doing. The old ones are hard to find now, and they can cost quite a bit on ebay.
