After playing the Minecraft map Portal Pioneers, a level from the map really inspired this suggestion.
Idea: A new mini game just like nether or secret base.
Players spawn in a temple with traps and they have to find keys to get outside of the temple,
getting out of the temple will lead players in the deep ocean where they will face deep sea monsters while trying to find Deep Sea Crystals that drops gems.
Kill the monsters to get gems and chances to get Sea Fragments which can be used with the npc to purchase items.
Shop Npc: Nordic Fisher Man, an npc that could be used to purchase new items.
Monsters: Sharks, Water Abyss, Davy Jones (boss), Mermaids, Octo Humans, sea worms, laval rocky horrors and more.
Here are some item ideas i drew:
-Ocean Sword
-Coral Hammer
-Water Jet Pack
-Water Abyss set (also the monster)
-Aqua Cherub Wings (or any water wing)
-a Complete shark set.
