The Mystery Cartoon Character Game, ongoing.

Ha, it's Olaf the Snowman from Disney's Frozen.

Yes, OUB, that's just who it is. I felt it was only right to honor that movie for its award. So you're up once again. Good job.

Good choice. Perhaps I can pick one about as worthy. Let's see ...

1) This character has appeared only once to date in an animated feature film, which won an Academy Award, the Oscar.

2) Though not the brightest bulb around, this character is a respectable fellow, and a loving, patient father.

3) This character is one of the good guys. Really. A good, decent man ... who just happens to be trying fervently to kill his wife.

I'm going to say it's King Fergus from Brave.

Well, Salty, if you're going to say King Fergus from Pixar's Brave, then I'm going to "that's correct."
To be fair, his wife, nagging control freak though she is, was transformed into a bear, so Fergus didn't recognize her. Fergus' motivation at that point ran along the lines of "I'm a-gonna kill th' bear what et me wife." So, regardless of whether ol' Fergus succeeds or fails, he'll be sleeping cold and alone for a while.

Good going, SB, that'll add another point, and control of the board.

Thanks OUB!

I have been in several movies and one TV special.
I had to experience interrogation.... twice.
My creator has a song based on him.

I'm thinking either someone from "Shrek" or "Toy Story," but can't find any characters that fit the clues.

You're on the right track emeraldisle.

I can't recall "Toy Story" characters being interrogated, so I'll play a hunch, and say Donkey from the Shrek movies.

Nope. Not Donkey.

...........

As I recall, the one being interrogated by Lord Farquaad was the Gingerbread Man. "Not my gumdrop buttons!"

And for what it's worth, Toy Story had an interrogation as well: nasty Sid, taking on a Gestapo persona, uses a magnifying glass and a sunbeam on poor Sheriff Woody. Sid gets called away by Pop Tarts before he can burn a significant hole between Woody's eyebrows.

The Gingerbread Man (Gingy) is correct OUB.

He was in all the Shrek movies and the Shrek Christmas special.
He was interrogated in both Shrek one (Lord Farquaad), and three (Hook).
His creator is The Muffin Man who has his own song.

Ah, I'm back online. Good fixing, Chief. Pesky machines always get the simplest instructions wrong.

Well, this vein has been tapped before, but I'll aim for a lesser branch ...

1) Though not a title character, this character has appeared in a goodly number of cartoons, both those produced to accompany feature films in theaters, and as stand-alone cartoons for television.

2) This character has had more than one voice actor, and has had more than one name. He's still the same character, though, because of how he functions in relation to the main characters.

3) There are cartoons where this character says not one word, and there are cartoons where this character does all the talking.

Well, I thought of two possibilities, but neither one is the right one, as both had more than one voice actor, but no name changes. So I'm stumped once again.

Yeah, the only name that comes to mind is a title character, so I know that's not it.

Tuffy/Nibbles, the small gray "sidekick" to Jerry in some of the Tom & Jerry cartoons?

Um, Tuffy/Nibbles is already on the Used Character list. I correctly guessed him a long time ago.

Big Nose from the Pink Panther cartoons has been guessed as well - but it must be someone like these types!

I'm racking my brains...

Ok, I have my fingers and toes crossed and hope I'm right about it being the Tasmanian Devil.

My, such splendid speculations.

IronCookuru tried Nibbles, who is also known as Tuffy, especially in the Mouseketeer cartoons. Mighty close posit, since Nibbles says nothing while a hungry orphan, but can't seem to shut up while a Mouseketeer. However, as far as I can determine, Nibbles has only the one voice actor. However, if I'm wrong about this, then this must count as an entirely correct answer.

PeterHale ventured Big Nose from David Depatie and Isadore "Friz" Freleng's Pink Panther cartoons. Aside from yelps and grumbling, I'm certain that Big Nose has never spoken, while the Pink Panther has at one point delivered the line: "Why can't man be more like animals?"

And EmeraldIsle fielded Freleng's Tasmanian Devil, a character which rarely speaks articulately, except for his debut cartoon: "What for you bury me in the cold, cold ground?" Not waiting for an answer, Taz simply opened his toothy jaws and tried to take a huge bite out of Bugs Bunny. Taz has appeared in other productions after the passing of the legendary Mel Blanc, of necessity voiced by other actors. However, he's known as the Tasmanian Devil, or as simply Taz; by "more than one name," I meant distinctly different, rather than derivative or diminutive names.

Therefore, I shall withhold the next set of clues until Nibbles' voice actor count can be confirmed. If there was only one, then I shall field the next three clues; otherwise, IronCookuru has scored another +1 for adhering to all criteria.

EDIT: Oops, since Nibbles is already on the Used Character List, that character cannot be regarded as correct. All the moreso, since I have a much larger character in mind. I'll post the next three clues when I return from dinner.
