Watruin

Watruin is the last planet on the road to Zythurvia in MarioMario54321's Super Mario 64 Bloopers movie The Cosmic Crystals IV: Zythurvia. It's watery ruins, though some towns managed to remain, one of which holds the Crystal Comet Medal. Rumors say that a secret aquarium exists. There are diamonds that alter the water level. The name is a pun of "what ruin" but with the first 3 letters in water in the name and combined It's mainly a retextured, reversed and recolored version of Wet-Dry World and the Hidden Aquarium in the same room as the Jolly Roger Bay painting. The Crystal Comet challenge was in the Secret Aquarium, and 8 Dark Crystals were to be collected. LuigiLuigi09876 did this and obtained a greenish teal Zyther Crystal.
