I don't own Harry Potter or Roger Rabbit.

Harry Potter and the Granger family flew with Merlin through the toonworld to Britain, as there was an entrance into this world in every mayor country. Roger and Jessica staid in America as they still had cartoons to film and they thought it was best not to show the British wizarding that toons existed. While traveling on the magic carpet (from Aladdin), who was happy to help them, the Grangers saw more of the toonworld than they had ever expected there to be. Eventually they left through a hillside opening close to Leavesden studio's and went to Merlin's old castle.

When they entered they were amazed by the beauty of the castle. Long tapestry's hung from the walls with depiction of battles and great warriors. In the great hall they found a round table and behind each seat there was a portrait of a knight. Their sword in their scabbards and lying on the table in a circle. Each member of the group was shown his/her room and was told to relax and explore, because the next day they would all go to Diagon Alley.

The next day when everybody came down for breakfast they had the shock of their lives, because Merlin didn't look like his cartoon self, but as how he looked like century ago when he helped Arthur in Camelot. He was softly grinning at the shocked faces on his friends faces and waved them to the breakfast table that had a complete English Breakfast waiting for them.

"Grandpa Merlin?" Hermione asked, "How come you look like a normal person instead of a toon?" "Well my dear, I thought it would be a good idea to look normal for where we are going. There is also the fact that they wouldn't have believed that I was actually Merlin, unless I looked like this." Merlin explained while watching as the people he saw as his people had breakfast. Hermione had been wondering what Merlin was going to do when they would leave for Diagon Alley.1

Once breakfast was over they all gathered around a rope that Merlin had enchanted into a Portkey and grabbed on. When they appeared in the alley they stood in front of a big white building. "Children, this is Gringotts bank. It is run by goblins and is probably the safest place in this world." Merlin explained while they walked up the stairs towards the doors. "In this world, grandpa? Do you mean that there is a safer place where Harry lives?" ( They had come to the conclusion that talking about the toonworld wouldn't have been a good idea, so they tried not to mention it) Hermione asked, just as inquisitive as always. "I think there is, if only for the different people that there." Merlin answers when they stand before the doors.

On each side of the doors stands a goblin in full armor. Written on the door it says:

Enter, stranger, but take heed
Of what awaits the sin of greed
For those who take, but do not earn,
Must pay most dearly in their turn.
So if you seek beneath our floors
A treasure that was never yours,
Thief, you have been warned, beware
Of finding more than treasure there.

Slowly they walked into the hall behind the doors. All became quite as the group walked towards the headteller. Quickly people started to gossip around them saying things like: "Isn't that Dumbledore?" "No, he doesn't have the right glasses." And "Is that Harry Potter?"

"May your enemies tremble in fear." Merlin said politely. "And may there blood paint your path." The goblin teller answered with respect. "It is not often that a wizard knows our greetings wizard. What can I do for you?" "May we access a couple of vaults and maybe see an accountant manager, goblin warrior?" Merlin asked with a solemn look. "Of course sir, may I know which accounts you want to look into?" the goblin asked sternly. "The Emrys and Potter accounts would be a good idea I think." Merlin said, having a smile on his face when he said this.

I'm sorry that this one is so short, but I really wanted to do a cliff-hanger. So for compensation I will explain how Merlin came to be a toon in America, while he started as the high wizard of king Arthur.

After he had been Arthur's most trusted adviser for years Merlin felt that his time was nearing, so he did a ritual he had been researching that would change a person, body and all, into a living portrait. The difference with moving portraits that were common in the wizarding world is that his portrait would know everything he knew and would in a certain way make him immortal, what he hadn't expected was how far the change would go.

In the years after his "death" he saw how his family and friends mourned his death, but they also all promised to his portrait to make his teaching live on. His four priced students started a school for all the young witches and wizards in the world, so they all could learn from what he had found.

In the meantime, his portrait staid in the Emrys castle where he kept on advising his family. What he hadn't told his family though, was that he could come out of his portrait and research further, leaving hints for his family. He had promised himself that he would only tell of his true powers to the one who could figure out his secret.

In the end it was a squib descendant who figured it out. He was the first squib in the Emrys family and though his family still loved he wasn't as cared for as his siblings. One night he went downstairs while the rest of the castle was asleep and knocked on the frame of Merlin's portrait and asked "Grandpa Merlin, could you give me a hug please, I know you could do that?" Merlin woke up from his slumber and gave a small smile before walking out of portrait and giving the young man a hug. After that night young Kepple would often be found talking to the old wizard.

When his eleventh birthday came and went without him getting a Hogwarts letter his parents came to the conclusion that he should leave the castle. They sent him to Irish friends of theirs who adopted him into the Disney family as they didn't have children of their own. His parents told him he could take one thing with him into the muggleworld and he asked for Merlin's portrait. As Merlin wanted to go with the young man the family allowed it and Kepple went on his merry way.

In the years after that the Disney family would emigrate to Canada and in the years after travel America. The living portrait would be kept a family secret that would only be told to the wives and husbands after their marriages had taken place. Eventually the son of Kepple, Walter, would ask his many great-grandfather whether he would like to go watch a cartoon with the young boy and Merlin agreed. What Merlin hadn't expected to happen was that the door and the back of his portrait would open and the cartooncharacters from the film he had seen with Walter all came to talk to him. They told him that they knew of the human world and would like to interact with it to make better films, but that they couldn't without a portal.

Merlin immediately started researching potential places for a portal and after years of researching the ritual he had to do for the portal to be stable he came upon a crosspoint of multiple leylines beneath a hill near Hollywood in California. When Walt moved here to start his cartoonstudios Merlin went to work. He made the first portal to toontown and thus toonworld.

Once Merlin went to toonworld for the first time he changed into a toon himself and was happily surprised, but knew that he could be a valuable help to his grandson in this form as he could tell Walt of the ideas that the toons had. In the end the toons started to interact with more people and whenever a new character was drawn they would shortly after appear in toontown, oftentimes with a passport saying they were employers of the company that made their drawing.

I hope you liked this explanation and I would love to explain other things that you might wonder about.
