Hokulani Observatory Trial Guide – Pokémon Ultra Sun and Ultra Moon

After completing the trial on Island Kahuna and advancing through key story events, you’ll arrive at Ula’ula Island. Your next challenge is the Hokulani Observatory trial on Mount Hokulani. This Hokulani Observatory Trial guide will walk you through each step, making it easier to complete.

How to Reach Hokulani Observatory

Mount Hokulani is accessible via the bus on Route 10, but before you can ride, you must visit the library as part of the story. Once that’s done, head to the bus stop at the end of Route 10. You’ll need to battle two Team Skull grunts before you can board. After defeating them, take the bus to the top of the mountain, where you’ll find Hokulani Observatory.

How to Complete the Hokulani Observatory Trial

When you enter the observatory, you’ll learn about the Charjabug power system. Before the trial can begin, you must gather all the Charjabug.

Finding the Missing Charjabug

Three Charjabug are missing and must be found outside the observatory:

• Two are hiding in the bushes in the central lot outside.
• The last one is next to the bus, visible in the background of the earlier cutscene.

Once you’ve collected them, return inside to start the trial.

Solving the Charjabug Puzzle

To summon the Totem Pokémon, you’ll need to align Charjabug in specific formations using four buttons to rotate their positions:

1. First Sequence – Create a straight horizontal line at the top of the roller.
2. Second Sequence – Create a straight horizontal line at the bottom of the roller.
3. Final Sequence – Form a diagonal line connecting the top and bottom lines.

Each successful alignment results in a battle:

• First Sequence: Fight an Elekid.
• Second Sequence: Fight an Electabuzz.
• Final Sequence: Summons Totem Togedemaru.

How to Defeat Totem Togedemaru

Totem Togedemaru is an Electric/Steel-type, making it weak to Fighting, Ground, and Fire-type moves. Using Pokémon that can exploit these weaknesses will make the battle easier. Once defeated, you’ll receive Electrium Z, marking the trial’s completion.
