This way by far the most challenging lego build to date. This set didn't come with instructions so I had to use instructions on the internet. I don't think it would have mattered either way, as back in the early 90's when they made this set, the instructions were very vague and had hardly any detail, which makes this 878 piece lego set a bit of a challenge.

Let's put it this way, there are only 31 different instruction points in the instruction booklet, compared to the "Up House" which only has 589 pieces, but has 213 instruction points in the instruction booklet.

Whew! It was fun, but challenging!
