Black-Mud Swamp
  • The Water Nymphs live in the Black-Mud Swamp. They are like tiny little mermaids and live in underwater bubbles made of a material that they produce from the leaves of the Xylith plant which grows only on the back of a giant turtle that was in a deep sleep because of a red willow tree that emitted a hypnotic gas growing on its shell.
    • Queen Algae is the queen of the Water Nymphs.
    • Lusiz is one of the Water Nymphs. She once went to pick Xylith leaves but fell into a deep sleep because of the red willow. The Winx defeated the tree and saved Lusiz.
