Rise of the Snakes
Rattla, along with Skales, Slithraa, and Mezmo were unlocked by Lloyd Garmadon, and was one of the snakes that thought Slithraa/Lloyd's plan was genius.
Rattla, along with other soldiers and scouts, helped build Lloyd's treehouse fortress.
Rattla, while on the Serpentine bus, tried to hypnotize Zane, only to be defeated with snowballs in his eyes.
He has the same head mold as Skales Jr.
