Zolly is a sleepy bat. The name comes from the Korean word 졸리다, meaning sleepy, with the final syllable dropped. Like a bat, Zolly works at night and sleeps by day. But Zolly never adjusts. Always tired, always sleepy. The brown pants are part of a work uniform worn by workers in the KIHOJISE universe. Zolly's outfit is hanbok, traditional Korean dress. It's worn as everyday clothing, and it doubles as flight wear.
