I didn’t call this a walkthrough because there’s no quest, but there is a new advertisement on some of the Poptropica islands for the new movie, Astro Boy. You can find the advertisement building in the usual place and when you go inside you can watch a movie trailer, play a quiz game, or get free costumes.
The trailer is kind of boring and the quiz game is pointless. You don’t get penalized for a wrong answer and there’s no prize for winning it.
There are two costumes up on the top of the room. You need to run up the ramp to see them and then click on the costume dummies you see to use the costumizer to wear them. Overall, this is not a very exciting advertisement mission at all. You’re better off creating a girl character and doing the Tinkerbell and the Lost Treasure Quest instead!
