I'm a FLOWER. I guess."
– Boogie introducing themselves
Boogie is the first character you find, they tell you how things works in Underground.
- The original version of Storyshift Flowey wasn't all too different from canon Flowey. Only a few lines of his dialogue were changed. On October 21, 2016, Flowey was redesigned as "Boogie" and their original identity of Napstablook became clearer due to prior confusion as to who was in Asriel's role.
