The Mystery Cartoon Character Game, ongoing-ier.

Thanks, Pete. Now as my Christmas present to everyone here, I give you a no-brainer:

1. I'm the last of a fearsome foursome.

2. Unlike the others, I only communicate by body language.

3. I convince the protagonist to repent by showing that both he and a little boy are six feet under.

That's easy as anything. The ghost of Christmas Future from A Christmas Carol.
1. Scrooge gets visited by four ghosts that night--the first being Jacob Marley, his deceased business partner, then the ghosts of Christmases past, present and future respectfully.
2. Generally the Ghost of Christmas Future doesn't talk--which makes him rather spooky--although there are some versions (I think the Disney one with Mickey Mouse and the Jetsons ones) where the ghost does talk.
3. For his last disturbing act, the ghost shows Scrooge that Tiny Tim has died--and so will him--by showing him their graves.

Good job, Glowworm. You're up now. Happy Holidays!

Thanks. I've actually read a Hanukkah version of the tale where the Scrooge like man is visited by three rabbis. The rabbi of the past is a traditional looking orthodox rabbi, the one of the present is more modern looking, and the one of the future is a woman.

Anyway, here's one to wrap your head around.
1. I was originally created to accommodate a rather unusual sound effect.
2. I later became a mascot character to a mobile phone content provider--they sold me as a ringtone.
3. However what probably made me the most (in)famous would be a hit single in which I "sing" along to a remix of the theme from Beverly Hills Cop.

I know this, but this time, I'll let someone else answer.

This is Crazy Frog, the mascot for Jamba. The sound effect was of a two-stroke engine.

Yep, it's Crazy Frog--originally called "The annoying thing."

Ok, here I go.

I was in two shorts. One was very different from the original story, and the other was closer.
I was unknowingly separated from my real family.
I was treated cruelly by everyone.

I definitely know this. It's The Ugly Duckling.

That's it! The 1931 The Ugly Duckling short was not true to the story, but the 1939 one was closer.

You're up again.

Thanks, Salty. Now for another untapped one:

1. I literally have wild schoolmates.

2. I end up at my school due to a typo--one that mistakes me for the king of the beasts.

3. I'll bet one of my classmates will be looking forward to 2016---it's the year of his species.

Ok, last three clues. Hope these make it easy:

4. I'm one of many cartoon characters named after the first male human mentioned in the Bible.

5. As per my show's title, I meet one of my new friends in Phys. Ed.

6. My animated series premiered on Cartoon Network ten years ago yesterday.

I've known this one since the first three clues--but had to go to work, and did not have time to answer. That and I was certain someone else would answer this one before I got to it.
This is Adam Lyon from My Gym Partner's a Monkey.
In my honest opinion, this was not a very good cartoon.

Glowworm, you got it! Good job! You may take your turn.

Thanks, I've seen bits and pieces of this show out of boredom or randomness, but I just never got into it. Also, I always thought the gorilla character looked rather stoned.
Anyhow, here's another character from another show I never really cared for--but will put up for the sake of this game.
1. We are inseparable.
2. This is meant literally, we are physically attached to one another.
3. Probably the most common question most viewers wondered about when they watched us was how the heck we went to the bathroom.

Right away, this has to be CatDog, created by Peter Hannan for Nickelodeon. I think at one point, the problem mentioned was resolved by "We take turns." Of course, in cartoonland, Nobody Poops, so this doesn't seem to be a problem for them at all.

Yes, this is Catdog--I've never liked this cartoon--it was usually extremely gross and mean-spirited most of the time.
Also, please forgive me if I post this little clip in regards to the last clue I stopped watching Family Guy quite some time ago, but I discovered this clip and totally agree with Peter.

Goodie, a chance to field a real Christmas character. Sort of.

1) This character is in the public domain, and has been portrayed any number of times, both live actors and animated.

2) For this purpose, I'll be cluing in on an animated feature version that debuted in theaters on Wednesday 25 December 1963.

3) Being such a young fellow, this character would normally be raised and taught by his father. Alas, this character is portrayed as an adoptee, being raised by a foster father. However, this character's schooling comes from an outsider, which proves rather fortunate.

Way too easy. It's King Arthur, AKA Wart, from "The Sword In The Stone."

Oh dear, "way too easy"? I must be doing something wrong. Yes, this is Arthur, from Disney's The Sword in the Stone, which debuted on Christmas Day of 1963. Sir Ector is his foster-father, and he is schooling Arthur in being a squire to a knight. However, that's as far as Arthur's education would go, except that the peculiar wizard Merlin intervenes. Merlin introduces young Arthur ("Wart" to his step-brother) to the mechanics of being a fish, a squirrel and a sparrow. If nothing else, it broadens Arthur's perspective.

So, here's an easy +1 to EmeraldIsle, plus control of the board.
