Unit 437 is a minor character of Slendytubbies III, that can be encountered during Chapter 2 - The Journey.
It's a mechanical humanoïd with two knives-hand and one orange eye. It has gears all over its body.
Unit 437 is encountered during Chapter 2 - The Journey, if the player chose the Teletubby Mountains.
It was a robot soldier sent to find and kill Yeti Tubbie but when it realized that it couldn't beat him it decided to become his servant. It now cuts trees to keep Yeti Tubbie's fire and cooks the food for him.
Its fate after The Guardian's evasion is unclear but according to what it said, it has been presumably destroyed by Yeti Tubbie.
They slowy walk towards the player and slice their blades when close. After losing half health, they start spinning their blades in a 360 degree motion, moving extremely quickly. They have a decent amount of health and can be deadly if not taken care of.
- Before the release of Slendytubbies III, The Security Droids were thought to be Voice Trumpets.
