Discovering the Prophecy of Good and Evil/The Quest of find the heroes begin

Here is how the prophecy was discovered in The Overlord Unleashed.

Later, SpongeBob found a prophecy of Good and Evil.

SpongeBob SquarePants: Master Shifu, look! There's more on this scroll.

Shifu: It can't be, I don't remember reading it before. Unless... it was developed by Oogway's spirit.

So, they read the Prophecy of Good and Evil.

Shifu: The Balance of Dark and Light can't be destroyed, and only the chosen heroes of pure good will stand against all evil. And only the Dragon Warrior, the Ten Heroes of Equestria, the Pillars of Old Equestria, the Twelve Apprentices of the Mane Ten, and the Heroic 6 of Bikini Bottom can unite the Eight Heroes of Chima and Nine Ninjas of Ninjago and defeat the Dark Lord.

Po: Like us!

Twilight Sparkle: We saved our realms many times before!

Star Swirl the Bearded: But wait... the Dark Lord? Is it the Overlord?

Sandbar: Possibly.

SpongeBob SquarePants: Then, we must be the ones who fit the bill.

Shifu: But it would require a map that will lead us to Chima and Ninjago.

Then, Sunburst brought out another scroll from the same spot Shifu found the scroll.

Sunburst: And it looks like we're in luck, Shifu. Look at this, it's a map that leads us to them.

Princess Celestia: Then we shall begin our quest for Chima and Ninjago. And if what Oogway say it's true about the prophecy, then we must ensure that they'll help us stop the Overlord.

Shifu: We shall make sure of it, Princess Celestia.

Capper: Then what're we waiting for? Let's go!

Po: Oh yeah! Whoo!

At last, the Quest for the two groups of heroes begin as everyone pack their equipment and begin their journey.
