Bathroom Stall
The opening number establishes the world, informing the audience of the language the short film will use which is a musical in a very traditional 'show-tune' sense. It reveals the setting of the whole short and sets the scene for the rest of the musical.
Where I Deserve To Be
As with other traditional musicals, the next song is the I Want Song and 'Where I Deserve To Be' is a classic example of the protagonist revealing what he wants most to achieve, which in the case of Bathroom Stall is to get a promotion to work on the fifth floor.
Public Restroom Hell
With the world established and the desires revealed, the third song pushes us into our main source of conflict in the short: a character has no toilet paper, and is in what he eponymously refers to as "Public Restroom Hell'.
The Fifth Floor
Once the characters work together to resolve the conflict, it is revealed that can both get what they want and both end up pleased with how their interaction has panned out and thus begins a promising new friendship.
Bathroom Stall (Reprise)
The first and title song, 'Bathroom Stall' has a reprisal only this time both characters are happy with the outcome of their respective journeys and the musical short ends on a high.
