Winx Club Forever
In its normal state, the Flower of the Depths appears to have off-white petals and a teal center.
In its mutated state, the Flower of the Depths' petals turn lavender, its center goes from teal to indigo and it also has three black vine-like arms that can reach out and grab its victims.
The Flower of the Depths has only appeared in "Trix Tricks" when Stella, Flora and Musa were searching for the Gem of Courage. Initially, it appeared in its normal calm state, but when Tritannus' pollution infected it, it turned into a gruesome, mutant version of the flower and attacked Stella, Flora, Musa and their respective Selkies. Fortunately, thanks to Flora's Fall Vortex attack, it reverted back to its normal state and she, Stella and Musa were given the final clue to achieving Sirenix and finding the Gem of Courage.
In its normal state, the Flower of the Depths has the ability to communicate by moving its white petals in a certain pattern. Meanwhile, in its mutated state, the Flower of the Depths has the ability to shoot out beams of purple energy from its center at its targets. It is unknown if the flower has any defensive abilities in its normal state.
