There’s actually a reason why Rapunzel and Flynn Ryder appeared in the coronation crowd. Kirsten Bell and Idina Mendel, the voices of Anna and Elsa, respectively, all auditioned for the role of Rapunzel before it was given to Mandy Moore. The appearance of that couple was a nod to that. Plus, it’s not unusual for films to do cameos of their “predecessors.” (Case in point, in “Moana,” when Maui finally gets his hook back but can’t control what animal he turns into, one of the animals is actually Sven)

0:08 I noticed rapunzel

Corona is mentioned in some Frozen books as well so it practically canon that they are in the same universe if you consider media outside of the movies canon.

The Swing painting was also used in a Tangled concept art. And if you search the meaning of the original painting then it’s similar to how Anna had two lovers of Hans and Kristoff (but in the movie they didn’t paint the lover in the front of the swing)

I love the sugar rush easter egg
