If those other Lego Pikachu MOCs were too small for you, then this is the one you have been looking for. Dirk Van Haesbroeck was commissioned by Game Mania, a Dutch video game store, to build two giant Pikachu models. The end product stood 1.5 meters tall, which is just about 5 feet tall. Each giant Pikachu model is built with just over 25,000 Lego pieces. In the end it looks like these models were auctioned off for charity, with one of them going for €3,500, or $3,700. That puts it at 15¢ per piece.
The model is mostly hollow inside, but there is some supporting structure hidden around. In the build video (below) you can see a system of Technic pieces were used to hold Pikachu’s massive tail.
