A Disney fan has developed a theory linking the make-believe worlds of the animated films "Tangled," "Frozen" and "The Little Mermaid," and it's generating a lot of buzz online.

The new theory builds upon an earlier fan discovery of a link between the 2010 Disney film "Tangled" and the 2013 blockbuster "Frozen."

Disney’s "Frozen" reference comes in the appearance of two characters resembling "Tangled" protagonists, Rapunzel and Eugene, who are seen attending the coronation ceremony of Elsa, one of the main characters in "Frozen." Elsa is the Princess of Arendelle, who becomes a snow queen with the magical powers to create ice and snow.

The reference in "Frozen" led fans to speculate over what the connection between the two films might be.

Could it be that the King and Queen of Arendelle (from “Frozen”) were on their way to the wedding ceremony of Rapunzel and Eugene when their boat sank? And, fans wondered online, is this the reason why Rapunzel and Eugene felt obliged to attend Elsa's coronation ceremony?

Then last week, one fan went a step further, finding a connection between the two films and the 1989 Disney classic "The Little Mermaid."

She posted her theory to Tumblr.

If it's true that Elsa's parents were going to Rapunzel's return celebration three years ago (when the movie “Tangled” was released) when their ship sank, this may have caused Rapunzel and Eugene – Rapunzel’s love and eventual husband -- to decide to attend Elsa's coronation ceremony, the fan wrote.

"Guys, Kingdom of Corona is in Germany. Kingdom of Arendelle is in Norway. The Little Mermaid was near Denmark.

"What if that sunken ship in “The Little Mermaid” is the King and Queen of Arendelle's??" she asked.

In “The Little Mermaid,” the main character Ariel explores a sunken ship where she finds human artifacts that fascinate her. It is her fascination with the artifacts that lead, in part, to her decision to make a deal with the sea witch Ursula to turn into a human. After turning human, she eventually marries Prince Eric.

Since making her theory public last Friday, the post has been re-blogged on Tumblr more than 54,000 times.

So Disney fans, have you noticed any other connections linking different Disney films?
