(IM SORRY FOR THE BACKGROUND AND VOICE) You are Frisk. You were at a Xmas party with the undertale characters like Sans, Papyrus, Asgore, Toriel, etc in Sans and Papyrus home. Sans got drunk and fell asleep and it was getting late so everyone needed sleep. They tell you to get water when sans wakes up and everyone but papyrus leaves. A few mins later Sans wakes up but something unexpected happens.

A colorful ball looking bot here to cheer people up! He looks like the huge ball in the picture, but only the actual size is about 5ft 1. However you act to him he will communicate with any feeling possible.
