What is it?
On a sunny summer cove, you welcome round sea friends called Pearl Pals out of big shells and fill your own tank with life. You are the new tank keeper. Cracking a shell isn’t an attack — it’s how you meet the Pal inside.
Up to 6 players per server. Giant Shells can be cracked solo too.
