The Great Escape in Hot Pursuit/The Overlord found Nadakhan's lamp

Here is how the Overlord found Nadakhan's lamp in The Overlord Unleashed.

Soon enough, Po, SpongeBob, Twilight and all of their friends along with the princesses made a huge escape in hot pursuit.

General Cryptor: Get them!

The Nindroids activate their wings and fly after them.

Po: Crane!

Crane: I'm on it, Po! Flash, Rainbow, you guys ready?

Rainbow Dash: You bet, Crane!

Flash Magnus: You take the lead!

Crane: Wings of Justice! KA-KAW!

With his wings, Crane sends a powerful gust of wind into the Nindroids sending them flying away.

General Cryptor: They're getting away!

So, Cryptor and the other Nindroids retreated and report it to the Overlord.

As they did, he was upset of this failed attempt to capture the princesses.

The Overlord: What do you mean they got away?!

General Cryptor: It wasn't my fault, Overlord. That Crane was too fast compared to those two pegasi.

The Overlord: Your troops have failed, General Cryptor. But the Nindroid MechDragon won't.

Just as he brings out the Nindroid MechDragon, he discovered Nadakhan's lamp.

The Overlord: What's this? (realizing the markings) The Lamp of Nadakhan.

With one rub of the lamp, Nadakhan was released.

Nadakhan: At long last, I am free from the lamp. (notice the Overlord) Overlord, my new master. How may I serve you?

The Overlord: Help me gather the Alicron Princesses of Equestria in exchange for your revenge against the Ninjago Ninjas.

Nadakhan: Of course, Overlord. It will be my pleasure, I'll even grant you three wishes as well.

The Overlord: Good. (checking the Cutie Map) You can run, Princesses of Equestria. But you can't hide. (laughs evilly)
