Sythak
From Tardis Wiki, the free Doctor Who reference
Sythaks were giant snakes native to the swamps of Palliox, a planet near Trion. (AUDIO: Freakshow)
Biology
Sythaks are giant horned snakes with yellow and orange markings. They are described by Turlough as having blazing yellow eyes, though whether this is a trait of all Sythak is unclear. They are venomous and can be controlled by a flute-like whistle.
