How to get access to the discord server: try and apply for the grubhub delivery guy job, then fail obviously. Go back to Morshu, then you must ask him about grubhub, this will then remind him of a meme he saw in the discord server. This will prompt him to invite you to the server, letting you access it from his shop. (Be warned, the discord server is VERY DANGEROUS due to the mods, so be careful, though it is necessary for multiple key items and endings).
