Giga?!

My house got recently cleaned up and my mom found a two electronic thingo's. They used to belong to my brothers. I tried one to see what it was and how it worked so I put in a battery. It then made a really loud screeching noise for a minute and giga appeared on the screen. My brother than did something and he said: "You just got this thing!" (He wasn't pointing to the screen; He was pointing to the buttons.) Um... Then a wierd bunny thing appeared on the screen. It was cute until a map appeared. Soon, Giga appeared on the screen. I couldn't see the bunny by pressing button's anymore.

WHAT IS THIS?!

Well it's obviously a Giga Pet...=)
