The StoryTeller (1987)

The Storyteller had its special effects overseen by John Stephenson as the Jim Henson Creature Shop's 'creative supervisor', with Ron Mueck, Paul Catling and Stephen Norrington all acting as 'special creature designers' throughout the series. Noted fantasy illustrator Brian Froud also was involved in the series as a conceptual designer, but it's unknown how much hand he had in designing the various creatures.

All episodes had scenes of John Hurt's storyteller narrating to his talking dog, realized as a puppet that was later reused in the sequel series The Storyteller: Greek Myths. The Storyteller dog puppet was designed by Neal Scanlan and built by Jane Gootnick.

The Death apparition and demons in 'The Soldier and Death' were realized as puppets; Gary Pollard was especially involved in the skeletal Death puppet's design. The images provided can be found on Pollard's own Facebook page.

Several demon puppets were also constructed for the episode; these had animatronics underneath, allowing the faces to emote.

Some of these puppets made appearances with Jim Henson in the episode 'Monster Maker' of The Jim Henson Hour.

'Fearnot' had an anglerfish-like 'pond sprite'; presumably the lights were powered by a battery within the suit itself - it's hard to know what the full suit looked like, as the performer is half-submerged in water in all their scenes. The pond sprite was handled by Stephen Norrington.

'The Luck Child' had a beautifully designed griffin puppet, built to be larger than any of the performers interacting with it, with a fully articulated head as well.

An rabbit puppet was fabricated for 'A Story Short', with a slightly human-like face to depict that it was once human.

The humanoid hedgehogs in 'Hans My Hedgehog' were achieved via heavy prosthetics with leg extensions; different facial prosthetics were designed to show Hans' development, with his older self being more wrinkled in appearance.

Torso and face prosthetics were also used in 'The Three Ravens', for the brief sequence of three young boys grotesquely transforming into ravens. The behind the scenes images show the prosthetics more clearly.

The titular giant of 'The Heartless Giant' was a performer wearing a prosthetic mask, with mechanisms allowing the mouth to move.

The talking wolf in the same episode, meanwhile was a puppet, with a fully articulated head allowing it to 'talk'.

The Thought Lion in 'The True Bride' was yet another puppet, that required three puppeteers to operate; Henson was so impressed with it that it would be in many episodes of The Jim Henson Hour.

Ron Mueck oversaw the realization of the episode's trolls, which were performers wearing prosthetics masks fitted with animatronics inside the long jaws, allowing them to move, as well as complementary gloves.

The troll's daughter 'Trollop', was realized with a similar mask, but with more prosthetics going down to the chest as well. Again, I have not been able to find any behind the scenes or promotonal images of the Trollop prop, so these screenshots will do.
