Miguel knew this was a bad idea. So why did he follow them? To make sure his sister and cousin are safe? Maybe deep inside he's curious on what his nine-year-old cousin Luna wants to show them.

They wonder in the Land of the Unknown for what feels like hours. They are supposed to be at the palace with their family, but Luna and Mila had to break the rules and explore.

"This way," Luna said to her younger cousins.

"W-we should head back…" Miguel suggest.

"Come on you big baby! Don't ruin our fun!" Mila said, following Luna to some large purple bushes.

Miguel sighs and follows them. Luna pushes away the leaves. "Follow me."

She went through the bush. Mila and Miguel follow her. They walk through the thick bush. Branches poke Miguel.

"Ow! Ow!"

"Shut up Miguel!" Mila snap.

"But it hurts Mila!" Miguel whine.

"Both of you shut up! We're here." Luna pulls the bush to let the twins go through. Mila and Miguel walk through the opening. When they crawl out, there jaws nearly drop.

"Whoa!" They both said together. In front of them is a lake with a waterfall. Beautiful blue trees surround the lake. Flowers glow into the everlasting night. It was truly beautiful.

Luna crawls out of the bush and stand up, flapping her purple dragon wings. "This, is the enchanted lake. I heard if you drink its water, you will see your future." She explains.

"Wow! I want to drink it! I want to see if I become a knight!" Mila said while running to the lake.

"Be careful with Kappas!" Luna shouted.

"What the hell is a Kappa?" Mila asks while still running.

"It's a Japanese folklore that live in lakes and rivers and they drag children into the water and eat you!" Luna calls out.

"Psh. Please, I'll be fine!" Mila walks up to the edge of the water. She kneels down on the mud. She puts her hands into the water. The water is cool but not cold. But then Mila screams.

"Aaaaaaaaaahhhhhhh! Help me! The kappa got me!"

"Mila!" Both Miguel and Luna shout and run towards her. But went they run close to her, she turns to them and pulls her arms out of the water.

"Ha! Got you!"

"Mila!" Luna said angrily.

Mila laugh. "You should see your faces, they were…" Mila felt someone grab her arm. Something sliming. Miguel and Luna's both froze. Mila turns to the water. A green webbed hand hold onto her arm tight. A head pops up from the water. A salamander humanoid creature with a beat and flat plate on his head look straight into Mila's eyes. He went back underwater and pull Mila in.

Luna and Miguel grab onto Mila and try to pull her out of the water, but the kappa is pulling her in. The two kids pull Mila as hard is they can.

But then another kappa came out of the water, revealing its large shell. It grabs onto Luna and tries to pull her in.

"Mila! Luna!" Miguel shout. Then a third kappa comes out of the water, he spots Miguel. His eyes widen. He doesn't want to let go of his sister, but if he stays, he will be pulled into the water too. The third kappa walks out of the water and walk towards Miguel. Miguel starts to cry.

Just then two black skeleton horses appear. Xibalba jumps off the horse and stabs the third kappa in the chest with his forward. The third kappa fell on the ground, landing on Miguel's feet. Miguel back away from the dead kappa.

Xibalba jumps into the water to find the two kappas.

El Chamuco stabs the second kappa and pulls his daughter out of the water, dragging her onto land.

Miguel turns back to the water. It became quiet. Miguel starts to cry.

"Papi! Mila!"

Salience.

Tears run down his white cheeks. "No."

But then Xibalba and Mila came up from the water, Xibalba taking a deep breath. He carry Mila out of the water and place her on land. He kneels next to her. "Come on honey, breath!"

Xibalba checks if Mila's breathing. When he discover Mila wasn't breathing, he immediacy went to work. He performs CPR on her.

Miguel, Luna, and El Chamuco watch as Xibalba panicking perform CPR. Finally, Mila coughs up water. She opens her eyes as she breathe in some air.

Xibalba signs in relief.

"Mila!" La Muerte, who watched the whole thing jump off the white horse and run to her. She kneel down and hug her.

La Noche got off her black horse and walk to her husband and daughter. "Is everyone ok?"

El Chamuco nod. "Yeah, we're fine." He then turns to Luna.

"You. You're in big trouble! It was your job to watch the twins and look what you've done!" El Chamuco snap.

Luna looks down on the ground. "Sorry Papi…"

"We will talk about this when we get back to the palace." El Chamuco said and walk to his horse.

Miguel walks up to his worried parents. "A-are we in trouble?" Miguel ask.

Xibalba looks up at his son. "We will talk about it when we get back."

"Mami, Papi, I drank some of the water. I get to be a knight!" Mila cheer.

"Oh no, you're not young lady!" Xibalba snap.

"But Papi…"

"Enough! We will talk about this when we get to the palace." Xibalba interrupted.

Mila and Miguel watch their dad walk to his horse and climb on it. He doses not look happy.
