Here is what I've called the PIKABOY, an idea which emerged in 2011 and that I eventually realised in late 2014. This custom features:
-LEDed Pikachu's cheeks when system is powered.
-Speaking Pikachu when system is both switched ON/OFF.
-180° rotating tail for both show off/playing position.
-Feet for STAND UP position.
-Elevated +, A & B buttons.
-Pokeball box.
