TELETUBBY SECRET LAIR
The Teletubby Secret Lair was originally the hiding place of the White Tubby. Unfortunately it got overran by Newborns, and now the roam the lair looking for victims.
TELETUBBY SECRET CENTER
The Teletubby Secret Center is a large factory-style building where the purpose is unknown. It's where Chainsaw Dipsy inhabits.
The teletubby lake is a swamp-like land located (basically) right next to Teletubby land. Lake Dipsy roams the map.
The Satellite station is a giant spaceship-style facility which looks similar to one of the maps from Dead Space 2. It has long corridors and is made mostly out of metal. It is located inside a mountain in the outskirts.
TELETUBBY LAND (DAY)
Teletubby land has been partially submerged in water due to rain every night. Most of it evaporated, but not all of it. The map takes place 3 years after the events of the original Slendytubbies, so there are the same "Landmarks" such as the dead Laa Laa, Po and Dipsy. There is light green fog present and the sky is cloudy and matches the colour of the fog.
TELETUBBY LAND (NIGHT)
This is the same map as Teletubby land (day) but at night time.
This map takes place far away from Teletubby land, hence the name. Laa Laa's mutant form is present here.
TELETUBBY TRAINING MAZE
This map is a large maze, and like the Teletubby Secret Center, the purpose is unknown. This is the most difficult map out of all of them. I recommend taking a screenshot if you beat it.
TubbyCraft is a Minecraft version of the original Slendytubbies map, but at daytime. It's exactly the same but everything is made of Minecraft-style structures and textures.
This map is the original Slendytubbies map, but at night. Classic Tinky Winky roams this map.
These maps are part of the 150K update, as thanks for 150K visits.
This place consists of canyons and dunes. There are 3 enemies roaming this map. Their information can be found on this page.
HIDDEN RESEARCH BASE
This map takes in the Teletubby cave in Slendytubbies 3. It is accessed through the pit (as seen in the Slendytubbies 3 campaign). My (tucannRBLX's) reborn roams this map.
This map is literally just underwater. That's it. There's a shipwreck and a greek temple. Deimos roams this map.
This map is an exact replica from the Slendytubbies 3 counterpart. The ghost girl roams this map.
