Koltin, younger brother of Kilton the Monster Parts Merchant, has become obsessed with Bubbulfrogs — creatures that live in caves across Hyrule and drop Bubbul Gems when defeated.

Step-by-Step Walkthrough

1

Meet Koltin

Koltin is first found near Woodland Stable in a green wagon at night. Speak with him and he will reveal his obsession with Bubbulfrogs and Bubbul Gems. He accepts your first gem and moves to a new location.

2

Hunt Bubbulfrogs in Caves

Bubbulfrogs spawn in caves across all of Hyrule — one per cave. They appear as glowing blue-green frogs on cave ceilings and walls. Hit them with an arrow or attack to collect the Bubbul Gem they drop. There are 147 total Bubbulfrogs across the game.

3

Trade Gems for Rewards

Find Koltin at his evening locations (he moves between different spots each time you trade). Each trade requires progressively more Bubbul Gems: 1 gem (Bokoblin Mask), 3 gems (Lizalfos Mask), 10 gems (Lynel Mask), etc. Rarer items require 40–60+ gems.

4

The Satori Connection

As you collect more Bubbul Gems, Koltin's obsession grows. Collecting 100+ gems triggers a unique conversation where Koltin references Satori (Lord of the Mountain) — hinting at a deeper connection between the cave creatures and the sacred mountain spirit.

5

Complete the Collection

Collecting all 147 Bubbul Gems and exchanging them all with Koltin completes his questline. His final reward is the Mystic Robe, Mystic Pants, and Mystic Headgear — the Mystic Set, which reduces monster parts consumed by Kilton's Fusing service.
