A super observer fan has managed to discover that Frozen, Tangled and The Little Mermaid movies are interconnected, that's the way it is and if you had not noticed, you will be surprised.
Remember that at the beginning of the Frozen movie, during the song "For the First Time in Forever" when the castle doors open for the coronation of Elsa and Anna? Watch carefully? ... That's right, they are Rapunzel and Eugene de Enredados!
What if the king and queen of Arendelle were on their way to the wedding of Rapunzel and Eugene when their ship sank and why Rapunzel and Eugene felt the need to go to the coronation ceremony of Elsa as a sign of respect ?.
Frozen does not tell us where the king and queen of Arendelle were going, we only saw Elsa asking "Do you have to go?" And Anna saying goodbye with a "See you in two weeks." But we know that they traveled by boat and what happened to that ship: The lines of time also coincide, after the shipwreck and the funeral, Frozen jumps to three years later? It will be just a coincidence that they were also three years of the premiere from Tangled to the premiere of Frozen? Enredados was released in 2010 and Frozen in 2013.
So if it's true that Elsa and Anna's parents were going to Rapunzel's wedding three years ago when their ship sank, what was the reason why Rapunzel and Flynn felt that need to go to Elsa's coronation? Maybe it was a way to show respect.
In addition to Ariel never appeared to him a skeleton of some king or queen while it looked for treasures, and thus the question could be answered of definitive form.
