To get sand shells in LEGO Fortnite, you need to find and beat the crab-like rollers.

This guide will show you how to locate and take down their cousins the sand rollers and get the sand shells you need.

1. Look for sand rollers:

• You'll spot sand rollers in sandy spots such as the desert area (The Dry Valley) and shorelines (The Coast).
• They hide as a heap of yellow sand with a green plant that has a red berry on top. Keep your eyes peeled for these signs, as the attached picture shows.

2. Ways to fight:

• Sand rollers attack by rolling causing heavy damage. Dodge this move and hit them when they get dizzy after rolling.
• They also hurl mud clumps from afar so get ready to fight.

3. Getting ready:

• Equip yourself well and have enough health, because Sand Rollers are tougher than regular ones.

4. Attract with bones:

• Sand Rollers love bones. Place bones on the ground to draw them out of hiding and make them easier to strike.

5. Prize:

• You'll get one sand shell from each Sand Roller you beat, which is your main goal.
