Although at first he acts callously toward Sarah, when she tricks him into helping her through the labyrinth, they develop a budding friendship, and soon Hoggle finds that he has to overcome his cowardice and choose between that friendship and his fear-induced loyalty to the Goblin King.
Hoggle is also terrified of the Bog of Eternal Stench, which makes it Jareth's most effective threat against him.
In the film, people often have difficulty remembering Hoggle's name, and so the character is referred to as Higgle, Hogwart, Hedgewart, and Hogbrain.
- At the Museum of the Moving Image, Brian Henson spoke a little about Hoggle during production of the film:
- Early on in production, Hoggle had a camera in his stomach to allow Shari Weiser to see out from inside the puppet. Weiser apparently hated the system, and the camera was eventually removed. Unfortunately, this meant that she could only see out when his mouth was open. So whenever Hoggle was about to walk into a large object, he would always let out a loud grunt so Weiser could see what was ahead of her.
- The Henson Company was not aware that the puppet was at the Unclaimed Baggage Center: Henson had lost it while the puppet was on tour.
- Terry Jones was meant to do the voice of Hoggle while the puppeteers did the movements. However, after four days, it was decided this was too complicated to do, and Henson ended up taking over as the voice and principal puppeteer.
