Super Power Island - you chase the Copycat clones downstairs and upstairs, including one that is on a light just above the vault door

The vault door on Spy Island is a trick because the ceiling is open.The vault door in the bank on Super Power Island can be reached by jumping on the ledge to the right that has a Copycat clone on it. Then you can reach the one on the light fixture above.
Vault 112 is in Casey smiths garage once you activate the electrical switch and you will have the doors into the basement open and then you get into Vault 112 and are spoken to by a robo-brain or whatever, and you go into the machine after you change into the Vault 112 vault suit.
You can hear it after you beat the quest "Project Purity." You will hear a distress signal from the vault and if you listen to it you will get a new quest, "trouble on the homefront" once you walk into the door of the vault you will once again hear the Vault 101 PA system, not that there's much to hear. p.s. you have to be somewhere near the vault such as in Megaton to hear the distress beacon.
you find it in the building. go past the b.a.d guards and pass the dogs in the building. he is hidden in the vault.
There is not a poptropica 2. But it would be awesome if it was. Once you beat poptropica then you have to wait for a new island to come out.
