Laboratory

The Laboratory or "lab" for short is the first chapter in struggling, and is Troy's place of birth. It is by far the easiest chapter in the entire game, and is in fact, the starting point of the game. As expected, it goes with a scientific lab theme.

This chapter contains 10 Hats, and 7 exclusive achievements. The hazards happen to be the Swimming Mouth Creature, Pig Monster, Toxic waste, rats, and spikey fetuses. It is succeeded by cave.

The music in this chapter are: E = MC Rave, Spiky Fetus Dubstep, Mucus Circus, Lame Bossa Nova and Chasing Rats.

Laboratory I - Unknown
It is named unknown because this part has no name at all, this point is where we meet the ugly creature known as troy, an amalgam of hector and achilles. This is a relatively short point in this chapter.

Laboratory II - Nightclub of Nerds
Yet another short area in the game, and the first area in the game to be named. It showcases a room with a bunch of scientists, a microphone on the top, and a banner that say "congratulations dave".

Laboratory III - Lethal Specimen Facility
This is the first area in the game where troy is face with actual danger (excluding lab I if you choose to not get the first hat obtainable in the game). This is also is first and only encounter with the Swimming Mouth Creature, in which troy has to avoid it or get eaten, then after that, has to either accidentally release spiky fetuses that fall from the ceiling or avoid pressing the button an go on peacefully.

Laboratory IV - Late-Night Regret Department
This area contains a giant pool of toxic waste that troy can get over with a rope, then go to an elevator, in which he can either confront the pig or avoid it by reclosing the door and pressing the button.

Laboratory V - Irreproachable Ventilation Network
This area is one giant vent that even touches the storage room. This is where rats spawn and nibble on the brothers, and as the brothers continue to traverse the vents, rats swarm the vents in large numbers in which troy must escape or meet his demise.

Laboratory VI - Waste Disposal Wing
The last area of this chapter. Troy must use a magnetic machine and move giant scrap elsewhere and get himself across the pools of waste in order to gain access to a long pipe that leads to the cave.

Aftermath
After troy is done moving giant scraps to where-ever and going inside the giant pipe, he gets sent to the cave, and, more specifically, the mine of mistakes.
