Get ready for the Pixar fan theory that will blow your mind. Frozen, Tangled and The Little Mermaid are all connected.
Rapunzel and Eugene (from Tangled) attend Elsa's coronation in Frozen.
But it seems the connection between the movies goes further.
Three years before the events of Frozen, two things happened.
In the real world, Tangled was released. In the Disney world, Elsa's parents died.
What if Elsa's parents ship sank...on their way to Rapunzel's wedding?
The time frames match up. Also, then Rapunzel would be kind of obliged to attend Elsa's coronation.
But WHERE is The Little Mermaid, you ask? Look at the geography.
Arendelle (Frozen) is in NORWAY. Corona (Tangled) is in GERMANY. Ariel's Kingdom (The Little Mermaid) is near DENMARK.
So if Elsa's parents' ship sunk on the way to Corona, near Denmark...
...Then Ariel goes exploring in the shipwreck that killed Elsa's parents!
...so Frozen, Tangled and The Little Mermaid are all connected.
