Dragodon

Dragodons are wild creatures native to Magix's Wildlands.

Overview
According to Stormy, they are considered to be the most ferocious animals and Icy says they absolutely despise water.

Season 2
When the Trix's traps and other mind-controlled wild animals failed at capturing Bloom and eliminating the Specialists and Winx. Stormy suggests adding the dragodons to their mind=control because of their aggressive temperaments. Darcy is able to make it happen. The Trix then use them as transport and with their mind-controlled animal army, they march towards the Winx and Specialists' campsite.

However, they are unaware of the traps set in place just for them. The Trix, their dragodons and the other animals, are washed away by strong rushing river water after Timmy instructs Musa to take out their man-made dam with sound waves. The dragodons, after being in water, are no longer under mind-control so Darcy reinforces their cooperation and they return to their mistresses.

The dragodons are then instructed to crush Timmy by the Trix but are led through a series of traps that leave two out of the three dragodons out of commission. The last one is led atop of a tiny log cabin by Timmy. The animal's heavy weight and large size causes the log cabin to collapse and Icy is thrown off it, it then lays there unconscious.

As it is not seen afterwards, it can be assumed that the dragodons had returned to their homes.

Trivia

 * Its name could be a blend of "dragon" and "megalodon," meaning "big tooth" in Greek as they do exhibit a dragon-like appearance and have large teeth.
