Forma Fish

Set#81000
Bricks: 293

Forma Koi! This set was actually done as a fund me page. They had a lot of problems initially meeting delivery, elegidly a container with the final products fell into the water off a ship or something. But its a cool set. The crank makes the fish simulate swimming.
 

Designing the crank mechanism to make it swim
 

I bought the extended kit which came with 3 extra skins, including a shark!
