What Makes this set WOW?

Senior Ranger Rocket Launcher: An interactive mechanism in the mob's tail allows it to physically fire missiles, perfectly replicating the dangerous laser attacks from Minecraft.

Hidden Treasure Chest: The Ocean Ruins section has an ingenious stash of gold and emeralds that can be discovered by dismantling a section of the structure.

Unique Deep Sea Diver Minifigure: The set features a new Deep Sea Diver figure with an exclusive, detailed visor print on the helmet, not seen on previous models.

A rich cast of mobs: The set contains as many as 7 figures, including a dolphin, a tropical fish and two types of guards, which allows you to create a complete underwater ecosystem of the biome.
