yes that blimp is an actual lego part. i have it myself. it came with a johnny lightning set and can be used as a storage container. i have tried building something with the blimp and it usually turns out really flimsy. covering it with chains and nets is a good idea
I always liked the Steampunk stuff. I bought that rise of Nations weird sequel almost JUST to see the steam punk mechs and stuff. NICE! it needs interior pictures though, and no logo on the top. Nice creation, though.
