theres a window on the building on the outside and you can use your fan to get up to it or i think you can jump to it. but its the orange window and use your tools to get in:)
Go through a window outside of the club.
go on youtube
there is a window that is bolted down on the right hand side of the club, click it, unscrew the screws, the follow the... INVENTOR!!!
get the blue map and it shows you the places you can go.
The inventor goes near Holmes (underground), so when you see pst... in here! or something like that,that's where the inventor is (this is main street for your information in poptropica).
you go back to main street and go underground where the inventor is
you go on the big air balloon
you have to press fly then go any where in Naboti island or press float
It's easy. All you have to do is go back to your hot air balloon and go to early poptropica.
You go to your backpack, and click the jet button thing (that The Inventor gave you) and click on whatever place you want to go to next.
Go to the robot club (the one with the broken AC) and use your heat goggles. He is floating around on the top floor.
go back on the air balloon and leave
