Description

A glowing gem dropped exclusively by Bubbulfrogs — the strange frog-like creatures found lurking inside caves across every region of Hyrule. Bubbul Gems are the primary currency for Koltin's traveling shop, where they can be traded for rare monster-themed outfits including the Mystic Set and unique masks. Each cave in Hyrule contains exactly one Bubbulfrog, so collecting all Bubbul Gems requires systematic cave exploration across every region. The gems emit a faint teal glow and cannot be cooked or fused effectively — their sole purpose is trading with Koltin to advance his quest chain and unlock increasingly rare rewards.
