Pokemon Pikachu 2
This is a Giga-Pet but, in many ways, it is better. Pikachu isn't only a Electronic Pet, but is also a running buddy too! Pikachu senses movements and motions. When you jump, run, or walk you accumulate Watts, which gets you special items in Gold & Silver. You can even get a Rare Candy with 999 Watts. You can also get watts from playing games with Pikachu, which is fun to do! This was the second Pokemon Pikachu made, and this was improved in one way because it is in color.
