If you’ve spent any amount of time in The Legend of Zelda: Tears of the Kingdom‘s caves, you’ve no doubt come across the strange Bubbulfrogs, seemingly mystical creatures that drop Bubbul Gems upon dying. Despite the fact that they’re gems, you can’t craft anything with this key item, so what exactly do they do in TOTK?
To use your Bubbul Gems in TOTK, you must find Koltin, a strange dwarf-esque creature who thinks that monsters are misunderstood and dreams of turning into a Satori. You can find him just outside a cave very early in the game, just to the northeast of Lookout Landing alongside his brother, Kilton, who you traded with in the first game for masks.
Koltin will appear out of the cave, after which he will explain to you that he needs Bubbul Gems. Give him a Bubbul Gem, and he will give you a Bokoblin Mask in exchange, helping you to avoid confrontation with Bokoblins.
After this, Koltin will disappear and move on to a new location. To find him, you can head over to Tarrey Town and speak to his brother, who will point you in the direction of the Ulri Mountain Skyview Tower to the northwest in the Akkala Highlands.
Make your way towards Koltin and you will see that he’s opened his own shop up, which is where you can keep taking your Bubbul Gems. However, Koltin only appears at night; it’s fairly easy to change the time of day, luckily.
Here’s every reward for giving the Bubbul Gems to Koltin in Tears of the Kingdom:
Bokoblin Mask – 1 Bubbul Gem
Moblin Mask – 2 Bubbul Gems
Hinox Toenail – 2 Bubbul Gems
Mystic Robe – 3 Bubbul Gems
8x Fire Keese Eyeball – 3 Bubbul Gems
Lizalfos Mask – 3 Bubbul Gems
Ice-Breath Lizalfos Tail – 3 Bubbul Gems
Mystic Trousers – 4 Bubbul Gems
White-Maned Lynel Mace Horn – 4 Bubbul Gems
Horriblin Mask – 4 Bubbul Gems
2x Gleeok Wing – 4 Bubbul Gems
Lynel Mask – 4 Bubbul Gems
3x Gleeok Thunder Horn – 4 Bubbul Gems
Mystic Headpiece – 5 Bubbul Gems
Is it worth collecting every single one, does Koltin get his wish? You will have to wait and see, just like you’ll have to see how to unlock Popla Foothills Skyview Tower
