If you never left home without your Tamagotchi pet (or eight) during the '90s, then the gadget's new Apple Watch app is going to rock your world. It lets you revisit the glory days without colorful eggs hanging from your fanny pack! Simply download the Tamagotchi app ($1) to get started feeding, caring for, and loving your pets . . . all from the comfort of your wrist. When used along with the accompanying iPhone app, the watch edition gives you the full Tamagotchi experience. We can almost hear the toy's signature "alert" beeps now!
