Sand Beetle ShellEdit
The sand beetle shell is one of the first items you will need in Castaway 1. You can get one by killing a sand beetle on Castaway Beach. Sand beetle shells are worth three gold pieces. They are needed for two of the first missions of Castaway 1. One of the missions requires you to turn in eight sand beetle shells. The other requires you to turn in 20 sand beetle shells, and gives you a sand beetle shield as a reward.
Other types of shells include the grass beetle shells and black beetle shells.
