How to get shells in Lego Fortnite Odyssey
To get shells in LEGO Fortnite Odyssey, you need to find and defeat Rollers, which are crab-like enemies that hide in the grasslands biome. These enemies disguise themselves as small rocks with a little leaf sprouting on top and will attack you with rolling and lunging moves when you get close. The best time to strike a Roller is right after it finishes its roll attack and is momentarily stunned. Using a sword or pickaxe and dodging their attacks will help you defeat them more easily. Each Roller drops one shell upon defeat, which is essential for crafting and upgrading your village. Exploring the grasslands thoroughly and defeating Rollers whenever you encounter them is the most effective way to collect shells.
You will need to fight the rolling crabs found in the “grasslands” biome to get shells in Lego Fortnite. The trickiest thing will be finding the right kind of crab, because there are multiple kinds. We’ll walk you through step by step so you can make sure you find the find the right one.
First, go to the “grasslands” biome. Once you’re there, just run around until you bump into a large rolling crab. These crabs will either attack you, or you can spot them by looking for the big round rocks that protrude from the ground. They are less common than skeletons at night, but you should eventually bump into one while running around the biome.
In my experience, I only saw large rolling crabs spawn during the day, and had more luck finding them by the shores of lakes and ponds. They have a dome-like stone on top of their body that has little plants on it. You can see an image of what they look like below.

As you search, it’s important to stay in the grasslands biome because it’s easy to bump into other kinds of crabs. I saw small crabs that looked like spiders in the “shores” biome. These do not drop shells. You can also find biome-specific versions of the rolling crabs that look similar. These are not the same enemy though, and they do not drop the regular shells.
Once you find one, fight it. You can easily beat it with a shortsword or pickax and it will drop one shell. Continue the above process to find more shells. It might take some running around, but you should bump into them every now and then.

What’s the easiest way to find shells in Lego Fortnite Odyssey
The easiest way to find shells in LEGO Fortnite Odyssey is to head to the Grasslands biome and hunt down the Roller enemies-crab-like creatures that disguise themselves as small rocks with a little leaf or sprout on top. These Rollers pop out to attack you and drop one shell each when defeated. To efficiently collect shells, look for these disguised enemies throughout the Grasslands, including caves, and strike them when they are momentarily dazed after their rolling attack. Using ranged weapons can make the fight easier, but a sword and shield also work well. Be prepared for their projectile attacks and consider dropping bones nearby to distract them while you attack.
What’s the quickest way to spot and defeat roller crabs for shells
The quickest way to spot and defeat Roller crabs for shells in LEGO Fortnite Odyssey is to look for large round rocks with small plants or flowers growing on them, often partially buried in the ground, especially in the Grasslands biome. These rocks are actually disguised Rollers that will pop out and attack when you get close.
To defeat them efficiently, dodge their fast rolling attack by moving left or right just before impact, then strike during their brief cooldown period when they are stunned and defenseless. Using a sword and shield is effective, and it typically takes about eight hits with a Shortsword to defeat a Roller. Make sure to keep space around you to avoid getting cornered by their attacks.
By combining careful observation to spot the subtle plant details on their backs and mastering the dodge-attack timing, you can quickly and safely collect shells dropped by these creatures.
