Plug your MP3 player into the little white robot dog and watch it come alive — seven LED lights flashing across its face, ears wiggling, head bobbing to the beat. The iDog was the iPod era's must-have desk pet: part speaker, part Tamagotchi, all 2005.
The chunky gray robot dog that kicked off the early-2000s robo-pet craze. Poo-Chi barked, sang, and showed its mood through pixelated red LED "eyes," responded when you petted its head or spoke into its nose, and — best of all — sang synchronized songs with any other Poo-Chi nearby.
