Back in North Clock Town you’ll spot a boy with a red bandana shooting at a balloon. Pop this balloon with a bubble blast then talk to the boy. You need to find all five of them and fast, use your spin attack to hit them!
- North Clock Town - Northeast corner near the playground.
- South Clock Town - Underneath a crate in the middle of the area.
- East Clock Town - On the balcony of the Stock Pot Inn. Use the Deku Flower to reach him.
- Laundry Pool - Inside a crate near the bench to the left.
- West Clock Town - In the main plaza, north end near the Post Office.
Afterwards you’ll receive a code consisting of 1-2-3-4-5 but in a random order, the code is unique to you so write it down or remember it. Go to East Clock Town and speak with the boy guarding the secret base.
If you forgot the code for some reason talk to one of the Bombers. Input the code correctly to gain access to the Astral Observatory.
