I fully wish that Toei had included a filler scene between Wano Act 2 and 3 where Usopp gets rid of the frog on his head, Boingnosuke.
My hc is that Usopp had to let him go in a forest because he believed the Onigashima raid would be too dangerous.
I think it'd be most entertaining if Usopp is giving a tearful goodbye, but Boingnosuke just replies in ribbits, and occasionally tries to get back on Usopp's head. Usopp keeps trying to argue back like he understands its ribbits and eventually has to yell at it to go away.
Extra points would've been giving out if the filler scene included a flashback of Usopp saving Boingnosuke from a snake, as described in an SBS.
