I'll do the best I can:
The Storyteller: The Heartless Giant
(NOTE: The clothing style is a bit like like medieval wear, and European clothes.)
The Queen--I can't remember. I think she had long black (or brown) hair
Prince Leo--a 12-year old boy with black page-boy haircut and long nose
Prince Leo's Brother #1--has long black hair
Prince Leo's Brother #2--has long blondish-brown hair
The Heartless Giant--a longfaced costumed character, with short dark orange hair, moustache, and beard. Compared to Leo, he's roughly the size of a Gorg. He wore a baggy whitish shirt, brown vest and pants, and pointed shoes.
The Guard--I can't remember.
Lighthouse Island
Zeb Norman--a young man with black hair, blue eyes, red jacket, dark grey pants, and white sneakers.
Rosalie--a blond-haired woman with blue eyes, blue/white sweater, and sliver tail.
Clara Buford--a curly-gray-haired woman wearing a lavendarish dress and straw hat.
Fred--Jerry Nelson dressed as a scraggly-long-haired bum.
The Fortune Teller--I think she had long brown hair, and a wide-brimmed hat.
Sam, Jack, Carl Simms--I can't remember.
Monster Maker
Matt Banting--a teenager with black hair, brown eyes, and (ahem) big ears.
Alfie, Matthew's Dad--a blue-eyed man with short gray hair and beard. He has a sort of a "bug-eyed" expression sometimes, especially when he's threatening Chancey.
Jan, Matthew's Mom--has long black hair
Matthew's Teacher--has short brown/blond hair (I think)
Chancey Bellow--a middle-aged man with slightly thinning, longish grey hair
Periwinkle, Chancey Bellow's Wife--has slightly curly red hair.
Ben, Reg, Vaughn--I can't remember.
The Storyteller: The Soldier and Death
(NOTE: I'm not sure how to describe the clothing style.)
The Soldier--has brown hair, moustache, and beard.
The Old Soldier--If this is the same as the Soldier, then I'm not sure if he should be listed (since it's the same actor playing him).
The Drumming Beggar--I can't remember.
The Fiddling Beggar--I think he had scraggly long brown hair, moustache, beard, and a big smile.
The Soldier's Wife--I can't remember.
The Soldier's Son--had a blond page-boy haircut.
The Landlord--I can't remember.
The Devils--small, wiry devils (about the size of Prairie Dawn) with smirks on each of their faces, and a tuft of short hair on their heads.
Death--a blue-eyed creature with pale-colored skin. He looks a bit like a human, but not quite.
Should the Czar be added?--Probably, but I don't know what he looks like.
The Storyteller: The True Bride
Anya, the True Bride--a young woman with very light-colored hair.
The Prince--had brown hair tied in a pigtail, and sideburns.
The Troll--a hideous creature with a very long face. He has black hair, with a small pigtail at the top. His nose and mouth is at the end of his long face, and he has a ring through his nose. He also has two lower fangs sticking out of his mouth.
The Trollop, the Troll's Daughter--basically looks like the Troll without the ring, and with curly black hair.
There were a few "Prisoners" in the Trollip's castle who shouted out as to how Anya's cries could go unheard of. Should these be added to the list?
If so, please provide descripts if possible, and the human actors' names.--I can't remember.
And I think the White Lion should stay being called the White Lion.
The Storyteller: Sapsorrow
The King, The Crier, The King's Men--I can't remember.
Sapsorrow--has long, black hair. When Scraggletag, she had lots of hairy black fur, from head to toe.
For the stepsisters, I don't remember which is which, so forgive me if I get them mixed up.
Sapsorrow's Bad Sister #1--a large woman with black hair.
Sapsorrow's Bad Sister #2--has blondish hair and a long nose.
Straggletag, Sapsorrow's alternate identity when working for the Prince.
Should a separate entry for Straggletag be added or not?--Maybe you could list her as "Sapsorrow/Scraggletag".
The Prince--has semi-curly brown hair with sideburns.
Living with Dinosaurs
Dominick "Dom" Marshall--has blue eyes and blackish-brown hair.
Lee, Dom's Father--I think he had slightly thinning, short brown hair.
Vicki, Dom's Mother--a red-haired (or brown-haired) woman with slightly crossed eyes.
Adrian, Dom's Uncle--I can't remember.
Victor, Dom's Cousin--a boy slightly bigger than Dom, with black hair.
Dom's School Teacher--has long brownish hair.
Keith--If this was Dom's friend, then he is an African-American boy with short hair.
Dog the Dinosaur--a green dinosaur with a red mouth (and often bearing an upper row of teeth). He has white oval eyes with large black pupils, and moving brows. He has purple and yellow spots on his arms and back, and purple scales down his back. He also has a yellow stomach.
The Storyteller: The Three Ravens
The King--I think he had brown hair, moustache, and beard.
The Witch--has black hair, a sinister smile, and blue eyes.
The Princess--had blondish-brown hair.
Prince #1, Prince #2, Prince #3--all three had page-boy haircuts. Two had brown hair, and the oldest one had black hair.
The Three Ravens--probably shouldn't be counted since although they are different forms of the Princes, they are still the Princes.
The Prince--I can't remember.
2nd King--I can't remember.
The Three Baby Princes--I don't remember.
2 The Heartless Giant: The Magpie, The Salmon, and The Wolf.
Need descripts of these and whether they should be added to the list.
My point is that since they talked, thanks to the Storyteller's own narration, they should.
I agree. As for the other animals, they might be labeled as "Sapsorrow's Animal Friends".
3 Muppet_dk mentions a polar bear puppet present in Lighthouse Island.
Should this character be counted?--Maybe, maybe not. It didn't really have much of a role, but then again, how often does a polar bear appear near a lighthouse landscape?
The Secrets of the Muppets
Bamboo--you do know that this is the dog that played Jo-Jo, right? Would characters like that be counted on the list?
Also, what Muppets figures in your opinion would serve best for customs of the Solid Foam?--I'd love to see Digit, Flash, and Beard in figure form.
5 What differences in terms of description are there between the Story of the Hat-Sharpening King's King and the Hypocritic Oaf from its appearance on the Cosby Show? And are there similarly-differentiating differences between the Sandwich voiced by Jim Henson in the Secrets of the Muppets and the Disagreeable Sausage Sandwich from its appearance on the Cosby Show?--As it turns out, the Cosby Show episode was filmed at the same time as JHH (it wasn't until after his death that the episode would be dedicated to him).
--The Hypocritic Oaf and Hat-Sharpening King are the same puppet, but with different costumes.
--I see the Sandwich as more of a prop on JHH than as a character on the Cosby Show.
PS: Ringo the Dog probably shouldn't be on the list because it is the name of the real dog that played Pilgrim in long shots of KSY.
I hope that any or all of this has been very helpful for your list.
