to unlock the bad guys house
you use the key
use the battery key
there no key for poptropica
you use the key that the curator gives you on early poptropica and go back to the cottage and open the door with the key
You get the key from the bat, then there will be a back entrance, then you use the key there.
you dont use the key , you have to turn the windmill.
the best way is to use the key ring
later in the game you will need to go to the curator in early poptropica island , she will give you the key and go back and use the key to unlock the door
You go to the country side and go to the house then use the key to open it. glad to help:)
You get the translation key by jumping to the roof of the ruins. You use it to go through the door. By Alexis Wagenfeld
Catch the bat on the roof and use the key to get in the basement.
just use the key and it'll get down there
