Thelonious is one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the Shrek franchise.
Thelonious is the henchman of Lord Farquaad and possibly the executioner, as he's the one who tortures Gingy by breaking his legs and dunking him in the milk, as well as threatening the Magic Mirror by suggesting Lord Farquaad to break it. He is also the one who suggests Lord Farquaad choose Fiona, telling him to choose number three while holding up two fingers.
He is seen at Shrek and Fiona 's wedding and at Shrek's Karaoke Dance Party, where he seems to have become friends with Gingy; his former torture victim.
Thelonious appears in Shrek 4-D, where he has become the henchman of Lord Farquaad again, but during the story he turns on Farquaad and becomes friends with Fiona, Shrek, Donkey, and Dragon.
Thelonious appears at the end sitting in the audience of the movie theater in Far Far Away.
