I am just borrowing Supernatural and the awesome characters with much gratitude.

Sam and Dean, once again dressed as FBI agents, were standing at the crime scene where last night's lu'au took place.

"The man and this woman were entering the jungle," a witness said. "Next thing we heard were strangling cries and then nothing. We found the man drowned in a pit of poison and the woman was nowhere to be seen."

They went to the jungle where the found the poison pit. And suddenly, Sam had a huge suspicion on where that came from. "I think that poison stuff is phlegm," he said.

"From where?" Dean asked the younger Winchester.

Sam had an idea.

"A mo'o?"

The brothers were now in their hotel, back in Hawaiian shirts and jeans. Dean looked surprised as to what Sam told him.

"Don't you see?" Sam asked. "The tidal wave, the phlegm, it all fits!"

"What is a mo'o anyways?"

So Sam started schooling Dean on mo'os

"Mo'o are gecko-like creatures appearing in many Hawaiian stories. In one of them, Pele, the volcano goddess, sent her sister, Hi'iaka, to rescue a mortal lover. Three mo'o had captured him. As Hi'iaka journeyed, she found a bridge which turned out to be the man-eating mo'o Kikipua. She chased the lizard to his lair and killed it.

"Most mo'o are female, capable of shapeshifting into beautiful women or water dragons. They dwell in caves and ponds. According to legend, when fire was lit on altars, out would appear twelve-to thirty-foot long lizards, midnight black, in the water.

"As maidens, they can lure their victims into their own poisonous phlegm and drown them. They can attack ferociously. And if people trespass into their land, they will summon tidal waves towards them. So my guess is that that park that had the tidal wave was near the mo'o land.

"But get this, not all mo'o are vicious. Some are actually deities protecting the land. In fact, if one is killed, part of the land. Hawaii is littered with these.

"Mo'o are usually seen in caves, pools, and ponds. To tell if there is a mo'o, you need to look for either foam on the surface of the water or special stone markers erected to denote the habitat. Although it is kinda weird seeing giant lizards around here because giant lizards are not native to Hawaii."

"So basically, Hawaiian shapeshifters," Dean said. "How do you lure one?"

"You can draw them to the shore with fires lit on altars," Sam continued. "And then you just kill them how we kill ordinary shapeshifters, with silver."

"Okay, so there was one obviously disguising as a hot lady at that lu'au."

"And maybe that same one was disguising as a tiny gecko and washing all the trespassers away at that park. So tonight, we try to get through the park without being seen. Because there may be a mo'o cave nearby."

"Great. A jungle. Last thing I need. Nature."

Night had fallen, and Sam and Dean were now standing in the park, silver-bulleted guns and silver knives in their belts. They also carried fae-repellent materials in their pockets.

"I am not looking forward to this," Dean said.

"What choice do we have?"

So the boys started trekking through the park, down the opposite direction of the previous tidal wave's path.

I wanted to look for a Hawaiian monster that was practically vicious. When I learned about mo'o, I was hooked. Sorry this took me a while to update, but I had my own personal problems. I hope you enjoyed!
