Sir Robert Norramby is to appear in the next feature-length special, the Tale of the Brave.
The Ulfstead Castle estate owner, introduced in King of the Railway and voiced by Mike Grady, will play a role in the autumn special.
In a review of new Take-n-Play set Roar Dino Run at the New York Toy Fair, toy experts zooLert confirmed the character's involvement in a YouTube video.
The Earl tells him that those are the three missing bones he has been looking for so he can finish his megalosaurus.
The appearance of the said dinosaur species' bones plays a pivotal part in the monster themed plot.
Tale of the Brave: The Movie is coming soon to UK DVD and US Blu-ray in September.
