The Crunch Crunch Fried Shell is a craftable item in Lost Ark that requires you to have done a lot of the Tortoyk main quest. The main ingredient, the Egg of Creation Shell, is only found in the Body of Tortoyk dungeon, which is unlocked through the main story of Tortoyk.
Where to find the Egg of Creation Shell
The Egg of Creation Shell can be found at the very northern end of Body of Tortoyk Dungeon, right before climbing the cliff toward Tortoyk Village. You'll find it next to a bunch of sad blocks and Totoiki Captain. Just investigate the blinding light that you can walk into.
You must take this to Supitsu to craft the Crunch Crunch Friend Shell.
Supitsu is located in Mokoko Tavern, northwest of Whistle Plaza in Mokoko Village. She is located behind the fruit counter. You can make Crunch Crunch Friend Shell with 1,400 Silver. Once this is crafted, you can right-click the Crunch Crunch Friend Shell to add it to your Adventurer's Tome.
If you want to fill up your Adventurer's Tome, you can craft a lot of items, but we recommend only doing this one after you've unlocked the Body of Tortoyk dungeon. This is because you can get the ingredient while you finish the dungeon, making this fairly easy.
