Yeti Tubbie (a.k.a Mountain Tubbie in the game files) is a secondary character of the Slendytubbies series and one of its antagonists. He appears as a minor antagonist in Slendytubbies 2D.


He is a massive cyan teletubbie with a pale face and empty-looking eyes. He wears shoulder pads made of white fur and gloves of the same material. He has sharp teeth at the sides of his mouth, and blood on his left hand. He also noticeably has spiky hairs.


He appears as the sole threat of the Teletubby Mountains.

He follows the player while walking in a slightly faster speed. When the player is close to him, he will scream and speed up until the player gets far away enough. He emits an eerie voice. He starts to chase the player from a greater distance and also retires from a greater distance. He is almost as fast as the player when running and using the trees is a good way to escape him.


  • He is the most tenacious enemy of the game.
  • He is the only tracker who doesn't appear in the Training Maze.
  • Despite his appearance, he has a soft, innocent voice.
    • He actually fakes his voice to lure prey, which can be proved with his scream sounding different.
  • He is the only known teletubbie to have hairs.
  • The blood on his left hand could be explained by the fact that he punched The Guardian hard enough to cause him to bleed, in Slendytubbies III.
  • He, Tinky Winky, and Lake Dipsy are the only infected teletubbies who were shown be able to speak.

Please, the master will destroy me if it found out I let you go.
— Unit 437, Chapter 2.

Yeti Tubbie reappears in Slendytubbies III as one of the different threats, in both Campaign and Multiplayer.

He was an experiment subject, along with his friends Cave Tubbie and Arrow Tubbie


He has a similar appearance from the previous opus. He is a massive, yet rather skinny, cyan teletubbie with a pale face, spiky hairs and sharp teeth inside his mouth. He wears shoulder pads and gloves and, unlike the previous opus, doesn't have a bloody left hand.


He is one of the two possible threats of Chapter 2 - The Journey, if the player choose the Mountains.

He will introduce himself in a surprise attack, where he lures The Guardian with his fake voice and charge him, knocking him out and taking him in his presumed house. He has a servant known as Unit 437, which has to take care of him by preparing his meal and keeping him warm. After Guardian escaped, he notices his leak and starts to chases him. The player will have to listen carefully to his scream to go at the opposite way, otherwise it will be killed.

After this sequence, he is not seen or mentioned again.


In Collect and Versus, he appears as the sole threat of the Mountains.

Like other monsters, he will approach the closest Tubby Custard to the player and patrol around it, until he spots the player. When the player is spotted, he will scream and chase the player until all nearby players are far away enough or dead. He is rather of a threat due to his medium-speed attacks and the map is usually large and open enough to easily avoid him.

  • The player can find notes in the cave, which were written by an experimented teletubbie.
    • One of the notes shows a drawing where in it are: Cave Tubbie, Yeti Tubbie and Arrow Tubbie.
    • His droid explained that he escaped the lands, meaning he's most likely the one of the trio who ran away.
  • His fake voice is only heard in the campaign, before charging The Guardian.
  • He eats meat, which is something unseen with the others teletubbies, except the Brute Tubbies.
    • This could be just because his droid cooked him what it found, or just because he don't have the choice to survive.
  • He is ones of the four characters to not have more than one mutation, the others being: Laa-Laa, Cave Tubbie and Arrow Tubbie.
  • His nickname "Yeti Tubbie" is referring to him being a big creature from the snowy mountains, while his other known nickname "Mountain Tubbie" is just referring to the place he is roaming.
  • In the trio, each members seems to be the extreme of what they looked like before being infected.
    • They are bigger than the main four teletubbies on their first and only mutation, meaning they were probably originally bigger than them.
  • Despite being considered infected, he is showing signs of intelligence.
    • It may be that intelligence varies among individuals.
  • His servant tells at the Guardian that he escaped from the Main Land, meaning that him and his friends were presumably predecessors to the main four teletubbies in the Tubbytronic Superdome.
  • He shares his attack speed with Tinky Winky (both mutations), Undead Po, Dipsy Chainsaw, Laa-Laa, Ghost Girl and Evil Guardian.
    • His attack animation is faster and different when the player play as him.
  • The track Two Sides featured in the Sandbox Mode was originally planned to be his battle theme.
