Sully is in the left section of Steamworks island.
on planet earth
you dont .
In the garage next to Sully's shop
it is in sully's steam powered paraphernalia
Sully's Paraphernalia is just left of main street
go find sully the robot full of cold water
you have to get -5 on the steam battery
I'm not super sure what you use it for but I think it connects to the steam battery. I think.
To get the robot on poptropica you have to go to "SULLY'S STEAM-POWERED PARAPHERNALIA" and click on something you can get and the robot will wake up and follow you and then at some point in the game he will help you and he will not talk to you
After you get in Sully's shop,just ring the little bell on the left of the robot:)
Just to the left of Main Street. The living quarters it above the shop.
First, collect a key scattered around the island, such as Sully's Key. Click the lock next to the door. It will unlock the door.
