Details regarding a backstory and some ghostly characters have been released for Monstruos 3: The Ghosts of Latin America, an original house coming to Halloween Horror Nights 2025 at Universal Studios Hollywood.
Monstruos 3 House Details Revealed
Monstruos 3: The Ghosts of Latin America
The original house was announced via @HorrorNights on X (formerly Twitter) with the following details:
One wails. One bites. One beguiles. La Llorona, La Muelona, and La Siguanaba await in the dark. Three legends La Muerte wants you to meet, but you’ll wish you never did.
The first Monstruos house debuted at Universal Studios Hollywood in 2023, featuring The Monsters of Latin America — La Lechuza, Tlahuelpuchi, and El Silbón. Monstruos 2 featured The Nightmares of Latin America, El Charro, El Cadejo, and El Cucuy. Monstruos eventually made its way to Universal Studios Florida for Halloween Horror Nights 33.
Now, even more detail about the original house have been by the Discover Universal Blog.
New Details for Monstruos 3
In new details revealed for Monstruos 3: The Ghosts of Latin America, Discover Universal writer Alejandra Median shares that “legends of Latin America have survived for centuries and are as an integral part of our [Latin] cultures as our languages and history.” That being said, guests should prepare to hear terrifying and monstrous tales, much like an Abuelito would tell to “scare children into behaving.”
Prepare to meet our old friend Muerte, who will tell us of La Muelona, La Siguanaba, and La Llorona — each of these mythical women eager to sink their teeth into mortal flesh and hear you scream.
As Muerte would say, “Vengan, mis amigos. Let me tell you a story.”
El Cementerio de los Perdidos
The article included the first look at some new concept art, such as this piece of an overgrown cemetery:
This year, the third installment of the Monstruos series takes us back to the Cementerio de los Perdidos, which has been the setting for all of the previous Monstruos houses. However, as we look around, we’ll notice that we’re in a different part of the graveyard that we’ve never explored before. This is where children are buried and where our old friend Muerte is waiting.
Muerte
Universal described Muerte as the only original, non-folklore-based character for the Monstruos series. For this year’s house, he will be asking guests if they are afraid of the dark.
“Muerte is the only original character we created for the [Monstruos series],” says Universal Studios Hollywood creative director and executive producer John Murdy. “He’s the grave digger and caretaker of this place. He’s setting up the story for our guests as they’re waiting in line.”
This part of the cemetery is old. The once-bright pastel paint has faded and begun to peel off of the graves. The flower bouquets have all withered and died. The only things that seem to be alive are the mold that festers on the grave markers and a black cat that growls and hisses at the wind. As we watch, Muerte appears, carrying a lantern in one skeletal hand. He tells us of the ghostly monsters that dwell in this cemetery, the monsters that caused the death of all of these children: La Muelona, La Siguanaba, and La Llorona.
Fans of the Monstruos series know that Muerte is always up to some mischief. In years past, he spent the entire maze digging out a grave for us or spelling out his name using bones he dug up. This year, he’ll be following us through the house, while repeating a bone-chilling refrain: Are you afraid of the dark?
They also go into a little more detail concerning Muerte’s black cat, who will be seen in the cemetery for the first time.
As horrifying as his stories are, Muerte does have a soft spot: Oscura, the little black cat we’ll see in the cemetery belongs to him. “We thought, ‘Well, our fans have gotten to know Muerte over the last few years so why don’t we introduce something more about him that guests didn’t know,’” Murdy says. “He has a pet. He has a little ghost cat that hangs out in the cemetery with him.”
Oscura translates to “Darkness” in Spanish. And if that’s the darkness Muerte is talking about, it can’t be all that scary… right?
La Muelona
Moving on to descriptions of the actual ghosts for this third Monstruos installment, La Muelona is known for having large teeth or fangs.
Our first ghost comes from Colombia and Venezuela. She is known by many names: La Muelona (woman with big molars), La Colmilona (woman with big fangs), or La Dientona (woman with big teeth). You can probably see where this is going.
Because these legends were passed down orally over the span of centuries, La Muelona has many different origin stories. Some say she was cursed by her husband, who found out about her many infidelities. Others claim she was a witch who chose her own fate. Whatever her origin may be, one thing is agreed upon: La Muelona takes on the appearance of a gorgeous young woman in order to seduce unfaithful men. Once the men have followed her into the forest, La Muelona will produce her large, terrifying teeth and eat them alive!
La Siguanaba
Our next ghost, La Siguanaba, is described as having the head of a horse, but it remains hidden behind her long hair until she successfully lures an unsuspecting victim.
The story of La Siguanaba is one told throughout Mexico and Central America, with her name rooted in the indigenous languages of Mesoamerica. She usually appears to men, naked and beautiful, her face hidden behind her long, dark hair. Once she has lured men into the forests, she will finally expose her face, revealing the rotted head of a horse.
Most men who see her will die of fright or else go completely insane, doomed to wander the forests forever.
La Llorona
Finally, La Llorona has made appearances in past HHN events, but has an updated appearance for HHN 2025.
La Llorona is one of the most well-known Latina American legends. She has made several appearances in past HHN mazes. Her story begins as a young bride who gives birth to two children. When she finds out her husband is unfaithful, she drowns her children in a river in a blind fit of rage. After realizing what she’s done she becomes consumed with remorse and regret. She spends the rest of eternity wandering the earth, crying, “¡Ay, mis hijos! Oh, my children!”
Anyone who encounters La Llorona or hears her wails echoing throughout the night are in danger. There’s no knowing when or where La Llorona will strike. She’ll drag you to your death as she once dragged her own children down to the river.
John Murdy on Monstruos 3
This house is particularly important to Universal Studios Hollywood creative director and executive producer John Murdy. He appreciated the fact that “it gives a lot of Latino fans representation that they might not find at other Halloween events.”
“I love that we’re bringing Latin American culture to them,” Murdy says. “These stories have existed in Latin America for centuries and we’re bringing them to a modern audience. I think that’s just very cool and unique.”
And just because this is our third time in a Monstruos maze, that doesn’t mean it’ll be any less terrifying. “We’re going to switch it up for the guests this year,” Murdy assures. “We’ve trained them on how our Monstruos house is structured. So now we’re going to use that to our advantage and turn the tables. There’s going to be scares in places that they don’t expect, just to twist the knife a little bit.”
Halloween Horror Nights 2025 runs on select nights from September 4 through November 2 at Universal Studios Hollywood.
