Meeting the Heroes Of Olympus

Unrelated Theory!

DISNEY THEORY!!!!

Okay. Here it goes.

Hercules and Little Mermaid are tied because Hercules' father, Zues, has a brother, Poseidon, who has a son, Triton, who's got a daughter, Ariel.

From there, things get a bit more messy. In  the beginning of the Little Mermaid, we see Ariel snooping around in a sunken ship. Based on the geography of Norway passing over Denmark waters, the ship is supposedly the sunken ship of Agnar and Iduna. The parents of Elsa and Anna.

It is said that the king and queen of Arrendalle were headed to the Royal wedding of Rupunzel and Flynn. Even if that's not true, You can spot Flynn and Rupunzel during the song 'For the First Time In Forever.'

Hopping right back into the little mermaid, the King and Duke of Cinderella can be found at the wedding of cursed Eric and disguised Ursula.

That means, so far our chain is:
Cinderella–Little Mermaid–Hercules–Frozen–Tangled

From there, we can throw in Tarzan because of the Frozen Director/Tarzan Director stating he Tarzan is the Prince Of Arrendalle.

With Tarzan, we can add in the fact that Jane is supposedly a descendant of Belle. Boom! Beauty in the Beast.

Back to Tangled. The magical flower that helped Rapunzel be born, a duplicate of that flower can be spotted on Motonue. (Moana)

From there, allow me to point out that Crush and his spot can be found in the scene where Moana is a baby. Therefore, Finding Nemo/Finding Dory is also a part of this theory.

Recap: Cinderella–Little Mermaid–Hercules–Beauty and the Beast–Tarzan–Frozen–Tangled–Moana–Finding Nemo/Finding Dory

Wow. But wait! There's more!

From Hercules, we can add the extention of Lion King, due to Scar's carcass being a part of Hercules' base pose.

From Lion King, we can throw in A Bugs Life as you can catch Spot, if you look close enough.

Oh, and obviously, from Tangled, we can add in Sleeping Beauty and Snow White because they are a part of the selection of books in the library they visit.

In Snow White And The Seven Dwarfs, we can add Bambi, as Thumper can be seen.

From Frozen, we can add Big Hero Six as in the San Fran Sokyo Police Department a picture of Hans can be found.

In the same scene, there is a picture of Bolt on the policeman's desk. So, bolt is now in the mix.

Recap: Cinderella–Little Mermaid–Hercules–Beauty and the Beast–Tarzan–Frozen–Tangled–Moana–Finding Nemo/Finding Dory–Lion King–A Bug's Life–Sleeping Beauty–Snow White and the Seven Dwarfs-Bambi–Big Hero Six–Bolt.

Ok, so. From Finding Nemo, we can add in Monsters Inc./Monsters University. In the room of Boo, there is a Nemo Toy. Boom.

In the same scene as above a Jessie Doll can be seen. From that, Toy Story 1-3 can be added.

Taking Toy Story Three, you get the known villain, Lotso. Taking a Lotso toy, there is one of these said toys in a childs room during the scene when Karl lifts his house into the sky.

Therefore, our chain now consists of Cinderella–Little Mermaid–Hercules–Beauty and the Beast–Tarzan–Frozen–Tangled–Moana–Finding Nemo/Finding Dory–Lion King–A Bug's Life–Sleeping Beauty–Snow White and the Seven Dwarfs-Bambi–Big Hero Six–Bolt–Monsters Inc/Monsters University–Toy Story 1-3–Up.

This is just off the top of my head. There will most definitely be more.
