Mexico seems to be the theme of odd news this week, as the North American country has been the backdrop of many strange headlines raising eyebrows this week. From decapitated heads to sour-sipping hipsters, Mexico has certainly caused quite the stir lately. Here are the weirdest headlines to come out of the fascinating country of Mexico this week.

Two Human Heads Found In a Trash Bag

On Monday, the heads of two humans were found in Antunez, a town in Michoacán state in western Mexico.

Federal security forces found the heads in a trash bag. The Michoacán Attorney General's Office has yet to identify the victims. According to CNBC, officials suspect that the murders were the work of Knights Templar, a Mexican drug cartel. The cartel may have been trying to send a message to those considering betraying the gang and turning informant.

"This is what happens to all those who betray me," a cardboard sign next to the two severed heads said.

In the past, drug lords have used decapitation as public threats.

"We always took for granted that this kind of thing would happen -- it's a complex conflict," an anonymous official told CNBC in reference to the heads.

The heads were found outside of Paracuaro, which lies in the Tierra Caliente area. The anti-drug activists are currently fighting off Los Caballero Templarios, another drug cartel. According to Fox News Latino, members of the La Familia Michoacán drug cartel founded Los Caballero Templarios in December 2010.

Neither drug cartel has been proven to be associated with the shocking murder and warning.

Water Monster Almost Extinct From Xochimilco

Last week, news broke that Mexico's very own "water monster" is disappearing from the lakes and canals. The water network was once considered earth's "floating gardens" but is now suffering from relentless urban sprawl and pollution.

As a result, the axolotl, also known as the Mexican walking fish, is now "in serious risk of disappearing," Armando Tovar Garza, a biologist for Mexico's National Autonomous University, said.

The axolotl is identifiable by its long, slimy body, thick tail, protruding gills and suspicious smile. The salamander-like creature is hard to miss, but when researchers tried to capture axolotls last year, they came up empty-handed. Despite searching in shallow waters, Garza said the efforts ended with "four months of sampling -- zero axolotls."

The wild axolotl's population has been shrinking dramatically since at least 1998. That year, The Mexican Academy of Sciences reported an average of 6,000 axolotls per square kilometer. That number shrunk to 1,000 in 2003 and a dangerous 100 by 2008.

Still, researchers are not giving up hope. Over the last few years, scientists have built what they call "shelters" for the axolotl. This month, scientists will begin hunt for the water monster that will last three months.

"[The search] on almost all the canals have to be repeated because now we are in the cold season with lower temperatures, and that is when we ought to have more success with the axolotls because it is when they breed," Garza said.

Axolotls can reach up to one foot (30 centimeters) in length. They feast on small fish, crustaceans and insects. Axolotls get around by either walking with their four legs or swimming with their tails. Their average wild life span is 10-15 years.

Mexican Hipsters Make "Sour, Smelly and Slimy Aztec Brew" Trendy

That vivid headline came from NBCNews after GlobalPost reported that hipsters were taking over pulque. Only a few Mexico City bars sell the hip, increasingly popular drink (pronounced pool-kay). The weird thing about hipsters loving the drink, besides the fact that hipsters apparently exist in Mexico too, is that the description of the drink is repulsive.

Del Maguey describes pulque as "a milky, slightly foamy and somewhat viscous beverage made by fermenting (not distilling) the fresh sap of certain types of Maguey." Meanwhile, GlobalPost did not give the drink a much better review, depicting it as "the mildly sour, slightly slimy and gently fermented nectar of agave [which is the same thing as maguey]."

Pulque was originally popular amongst the poor. It comes as no surprise that hipsters are trying to chance what used to be a shameful poor man's drink into something that only hip kids know about.

"All kids," David Bravo, the bartender at Las Duelistas, a Mexico City dive bar, said of the bar's pulque drinkers. "Of every hundred people who come in now perhaps two or three are older."

At Las Duelistas, pulque runs at $1.65 a pint. According to GlobalPost, the drink is "nearly hangover-proof", which, from a drinker's perspective, makes the drink a steal.

Pulquerias are hard to find, making them even more alluring to hipsters. The prominence pulquerias in Mexican cities dwindled over the last century as beer became the drink of choice. Now, only a few dozen pulquerias exist in Mexico City.

"They treat pulque like a fad," Melly Leyva, a 46-year-old former pulqueria bartender, said. "They don't value it as part of our culture, our traditions. They don't know their history."

Aztecs used to enjoy pulque during both parties and religious events. According to Del Maguey, the drink goes as far back as 1,000 A.D.

"This is my roots," David Matute, a 33-year-old pulqueria veteran, explained. "Like 1,500 years ago, someone was feeling exactly like I do right now. The pulque has me."

Mexican Fisherman Washes Ashore After Being Lost at Sea for 13 Months

On Monday, José Salvador Alvarenga made headlines when he washed ashore on Ebon, a small atoll of Marshall Islands. The 37-year-old shocked the world when he told rescuers and Marshall Islands' U.S. Ambassador that he had arrived after being lost at sea in a fibre-glass boat for the past 13 months.

According to Alvarenga, he left Mexico in December of 2012 with a teenager named Ezekiel and ended up getting lost. Apparently, the fisherman survived over a year of drifting by eating fish, turtles and birds, before he finally made it to Marshall Islands, which is about 5,500 miles away from his departure point.

"It's hard for me to imagine someone surviving 13 months at sea, but it's also hard to imagine how someone might arrive on Ebon out of the blue," Ambassador Tom Armbruster said in Majuro. "Certainly this guy has had an ordeal and has been at sea for some time."

Alvarenga said that Ezekiel died a month after the voyage began.

Today, a rescue official from Chiapas Mexico confirmed that "a boat carrying two fishermen was declared missing two days after setting off on November 17, 2012," CBS News reports. When the story broke, however, it was reported that Alvarenga left Mexico on Dec. 21, 2012.

Alvarenga grew up in El Salvador and has lived in Mexico for the last 15 years. He fishes for a man, who he only identified as Willie, and catches sharks for 25 pesos (or about $1.87 US dollars) per pound.

Now, Alvarenga reportedly wants to go back to Mexico.

"He thanked God, initially, that he had survived," Ambassador Armbruster said. "He's very anxious to get back in touch with his employer and also with the family of Ezekiel. That's his driving motivation at the moment."
