Here is how the villains make their plot in Princess Yuna's Adventure Begins.
Meanwhile, Hades, Jafar, Ursula, Captain Hook and Oogie Boogie were watching in their watchful cauldron.
Hades: That little squirt took The Jester! Who'd have thought it?
Jafar: Such as the power of her magic. The Princess's strength is not her own.
Ursula: Why don't we turn her and her little friends into a bunch of Heartless? (laughs) That'll settle things quick enough.
Captain Hook: And the foals' friends are the royal lackeys. Swoggle me eyes, They're all bilge rats by the look of them.
Oogie Boogie: You're no prize yourself. (laughs)
Captain Hook: Shut up!
Maleficent: Enough. Princess Yuna, The Mane 6's foals and the rest of their friends were chosen as new heroes and heroines of one world to another. Will it be they who conquers the darkness? Or will the darkness swallow them? Either way, They could be quite useful.
Jafar: The time is right for each of us to be rid of Princess Yuna and her little friends.
Captain Hook: Right, Jafar. Who knows what greater things we're up against?
Ursula: Then, If any of us failed the next one will take care of them.
Oogie Boogie: Looks like we got us a vote to work on.
The villains evilly laughed.
Maleficent: I must warned them!
