i am not sure but maybe go to all the places where u can talk and battle and maybe you'll find it there.
Find your balloon
it is in any common room,it could take many tries to find it.
You do not need to find balloon boy and you can't find him
In poptropica on the third island on the third day of the week at 3:33 am or pm:)
at main street in the party place
Find it anywhere you can talk to online people.
You have to look in the poptropica store.... but it is Poptropica's 4th birthday, so you pretty much have to buy the balloons icon, which shows different emotions. yet it also shows other balloon things.
You get an ultra rare 3rd birthday costume!!!!!!!
The best place to find is on Time Tangled because its The third Island. I got lucky and found one it reality.
There is no balloon as part of the quest. There were some as parts of Poptropica birthdays. And there are balloons in the party at the end.
You can purchase it for free in the Poptropica Store.
go in your poptropica balloon and click on big nate :)
