Shelly Island

Shelly Islands are what you would've guessed; islands shaped like a literal shelly. Shelly Islands (Large) are the new spawn point for Shelby and her friends, Sheldon, and lil' Shelbert.

Location
Shelly Islands can be found near the edge of the map and next to one of the numerous floating islands in Booga Booga. Specifically, the Crystal Island.

Appearance
I won't add much to this paragraph, as I already wrote about this in the first paragraph. Again, Shelly Islands are what you would've guessed; islands shaped like a literal shelly.
