Pokemon Mini

Pokemon Mini is only 70g and can be held with just one hand!
Somehow, Nintendo happened to fit a Rumble Feature in that small package.

Only Nintendo knows why they wanted to make these instead of a GBA game (that really puzzles me)
This is about the size of a "Tomagochi" or "Giga Pet", but instead it takes cartridges! I think that is amazing personally. The cartridges are about half the size of a Game Boy Advance one.

Pokemon Mini comes in three different styles which are Wooper Blue, Chikorita Green, and Smoochum Purple. The retail price of just the Pokemon Mini system is $39.95 (US) and including all games it is $81.95 (US)
