Title: Koupen-chan’s “Wait, wait”
0:00:06.34: Ah!
0:00:07.66: Poppoppo-! (Coo coo coo)
0:00:10.82: Wait, wait--
0:00:15.74: Waaait
0:00:25.04: Original work: rurutea
Edit note: I previously translated “Poppoppo” as puff puff puff, but in this context it actually means “coo,” or the sound that pigeons/doves make. (Jisho) (Source about a children’s song about pigeons)(The original source).
