With Older Littlefoot and Older Ali eventually came Thunderfoot. There also came Arianna II, but I haven’t drawn her yet.
Thunderfoot is like his father and likes to go adventuring everywhere. He is the first generation of Longnecks from the migration of the Great Herd Migration of the 1st film to be born inside the Great Valley. He also, unlike his father and mother, is raised without the prejudice among the kinds that plagued the dinosaur world for so long. Also, he has Sharptooth, Egg Stealer, Bothtooth, and Flattooth friends.
He was drawn doing combination colors of young Littlefoot and young Ali. He has blue eyes like Ali but is more similar in appearance to Littlefoot.
