The Mystery Cartoon Character Game, ongoing.

Can't answer this one. Let the others here give it a shot.

The Easter bunnies from the Silly Symphony Funny Little Bunnies.

That's right peterhale! Now it's your turn.

OK - this character is not from an Easter cartoon, as such, but it is seasonally appropriate...

1) I'm the star of a theatrical cartoon series of ... one cartoon!

2) They don't like my playing, so I do a little rearranging.

3) When I promise I'll never do any such mischief again, I kept my fingers crossed!

I really and truly don't know this one.

Yeah, I'm drawing a blank. I'll be waiting for the next set of clues.

More clues it is!

4) I'm mythological, so I don't wear any pants.

5) My prank causes mass marital breakdown, leaving me to feed the abandoned babies.

6) My creators subsequently published my story as a book.

Still don't have it. I'll leave it up to someone else once again.

Hmm. I had an idea but it was a bust. I shall keep looking.

Last set of clues!

7) I was created by a Hungarian illustrator and his wife.

8) A similar character (although of much higher rank!) was featured in a 1930 Disney short -but he wasn't so mischievous! My kind also appear in Fantasia.

9) Unusually, I don't appear to have horns.

I checked all the 1930 Disney shorts, and Fantasia, and still came up with nothing.

It's Peterkin from the Walter Lantz short "Scrambled Eggs." I found it on youtube once a while ago by chance--didn't actually watch it--looked up a synopsis on it instead.

It is indeed Peterkin the faun.

Stand by for lengthy explanations...

1) As you identified, his only film is Scrambled Eggs - but the Peterkin card that precedes the title, along with his promise to create more mischief tomorrow, suggests Lantz was hoping for a series.

Lantz was making the leap to colour in 1939 - Scrambled Eggs is the third colour film; the first was L'il Eightball's A Haunting We Wil Go and the second was Life Begins for Andy Panda. The latter film gave him the star he needed to replace Oswald the Lucky Rabbit, but Universal were not prepared to pay what Lantz asking, so in 1940 he briefly closed his studio.

His regular staff stuck with him, but I suspect the Poganys, who had brought the Peterkin idea to Lantz, decided not to hang around, and took their character with them. The story was published under the title Peterkin in 1940.

2) The faun is playing his pipes, and is hushed at by the expectant parent birds in the "Maternity Tree".

3) As he explains at the end of the film, when he is washing the diapers.

4) Willy Pogany had painted fauns since he was a teenager, and depicted them with hairy legs but naked bottoms. In an interview with Hollywood Reporter Frederick C. Othman he said: "Fauns don't wear pants. I was worried about the censors in connection with this one, but I took it up with the Hays office and explained what I was trying to do, and they finally said go ahead, so long as I kept it artistic." (Although I expect it was the studio who checked with the Hays Office rather than Pogany himself!)

5) Peterkin switches all the eggs around. When the husbands find "cukoos in the nest" they retreat to their club, while the wives "go home to mother".

6) As previously mentioned.

7) Willy Pogany studied in Budapest, Munich and Paris, before moving to London in 1906, where he established himself as an art nouveau illustrator. He moved to America in 1914. Elaine Pogany, his second wife, is credited with writing the story.

8) The 1930 Silly Symphony Playful Pan portrays the 'great god' as a puckish faun. And Fauns feature in the Pastoral Symphony section of Fantasia.

9) Unless they are hidden under his hair!

Well spotted, Glowworm!

Had I seen this earlier than today, I would have spared you some of those clues, Peterhale. Glad I could crack this one before it went unsolved.

Anyhow, Here's one I've been wanting to do.

1. My life is narrated as if I were a person.
2. Just like a person, I had my ups and downs in life.
3. In the beginning of my short, I'm quite a bit of a flirt.

This is another I may have to look up.

I think this is Susie the Little Blue Coupe, from the 1952 Disney short.

Oh, Peterhale, you are good. It is Susie the Little Blue Coupe.

1. Susie's life is told as if she were a person rather than a little car.
2. Pretty much, Susie had good times, and bad times.
3. In the beginning of the short, it is mentioned that Susie would spend most of her day in the store window flirting with the people who walked by.

It was that third clue that clinched it!

Here's a character we've not had yet...

1) I've been animated by 3 different studios - 4 if you count the 3rd studio changing ownership.
2) All my shorts were in black & white except the last.
3) My girlfriend is a different species to myself.

This is another toughie. I'll need to look it up like never before.

I may have an inkling--but we shall see...
