# JR's swim costume

On the south eastern part of the map of Miltia is a small, barely visible side street heading south off the main street. Pass through that street and go to the east to find a treasure chest containing an armor for JR that changes his character model.
# Balloon girl and two Berry Ice Creams

In the center of Miltia City is a long west-to-east walkway, with the eastern end turning into another part of the city. There should be a breakable short red gate blocking a building. Destroy the gate and the door to enter the building. Climb the stairs to see a little girl talking about a cat who stole her balloon. The cat is walking back and forth along a horizontal flagpole. Use a trap to make the cat drop the balloon. Then, catch the balloon with Circle for two Berry Ice Creams (Medium HP restore).
# The Business District Gate code

Once you are able to move around in Miltia's map, go to the right as far as possible. You will see a treasure chest on top of a building. When you select this chest, text will appear asking for a code. The code is "5150".
