How do you make the mecha dog in My Sims Kingdom?

the first time you have to find him he is in the zoo by the alligator. He will lure the alligator away, then you go in and go to the ladder. it will take you down into this metal lab. when you hit the first intersection don't go, there's no need. just keep going straight and then take a left. The kid who messed up the town will me there. the second time you go to the ski slops. just go up to him and click A.
