How do you build the robots bridge at rocket reef on my sims kingdom wii?

First start over place the platforms first
Next place the side railings
Make sure you have the right size of pipe before u place them down
I not sure if I remember right but i dont think u need the archways
Double check to see of u have the rockets in the right direction
Tobar should walk across the bridge when u are finshed if he doesn't make sure nothing is blocking him
