Shells come in all shapes and sizes in Another Crab's Treasure, and the best part is that most of them aren't even shells. As you travel through the Shallows and beyond, you'll come across a variety of "houses" that protect Kril and aid them in battle.
Another Crab Treasure | All 69 Shell Locations | Shell Seeker Achievement/Trophy Guide
Each shell has a defense level and a weight, which determines your dodging and movement speed. Most shells you find in the game also provide an ability with an effect that can help you in combat. There are a total of 69 shells in Another Crab's Treasure, and you'll need to find them all before they appear in your collection.
But you won’t be able to find every shell at the start of the game. Certain shells spawn in specific areas that you can only reach as you progress through the game, meaning many of the items on this list will be withheld from you at the start of your journey. But for those curious about what else is in store for you in the game, here are all the shells in Another Crab’s Treasure, their stats, where to find them, and the names and effects of their unique abilities.
