This is Coki the Crocodile, my first Lego Idea.
Its just a little crocodile that can move its mouth and tail. Everything about Coki is simple, but it looks fun and can be a nice challenge for little new creators.
And why do you belive this would make a great LEGO set? Because its perfect in its simplicity. Its easy to build and can serve as a way for new builders to learn how to provide movement to their first creations.
I also think that it has an attractive design even though it does not have a high number of pieces.
You can change the colour of the grey piece for your favorite colour to identify your Coki!
