Noo Noo was a minor character during the first opuses, before being confirmed to be the true main antagonist of the Slendytubbies saga.
He thinks Teletubbies have to be murderous creatures, so he decided to infect the main supply of Tubby Custard in case every productions makes infected custards. He also put his virus into the "Teletubby Creation Machine" to create numerous teletubbies who are already infected.
In Slendytubbies II, he only appears in the Classic map, but this time, he looks normal, just cleaning the house.
Noo Noo makes his return as a major character. He only appears in the Campaign.
At the beginning, Noo Noo went to the beach to look for Po. The two characters then started to interact with each other. He then decided to stay there for a little longer.
After the battle, a discussion occurs with the two characters:
- If White Tubbie accepts to follow him, they'll go together at the Custard Facility.
- Noo Noo will then give a custard at White Tubbie, if the latter accepts to eat it, which will makes him become an infected. Evil Ending
- Noo Noo will order Po to push White Tubbie, if the latter refuses to eat the custard, which will makes him become the Crawler Tubbie. Regretful Ending
- If White Tubbie denies to join him, he'll send Po to fight him.
- Noo Noo and Po will leave the corpse of White Tubbie, killed, if the latter loses against the final phase of Po. Bad Ending
- If Po is beaten, Noo Noo realizes that this was his last chance and that he have nowhere to go. He then gets destroyed by White Tubbie. Good Ending
- He does not appear in Slendytubbies 2D.
- He was never seen as a major character until the last game.
- He is able to manipulate the infected teletubbies without being harmed by them, especially Po.
- He created an army of New Borns.
