This scene with Bonta-Kun from R: Bonta-Kun clears a path for the team; Klan, Zero, Kallen, and Ryusei are surprised at it appearing, as well as trying to figure out what the hell it is; Silvia, Tsugumi, and Autumn just fall in love with it, with Sylvia saying she wants to "fumo fumo" with it.
R, being on the PlayStation 3, introduces a set of trophies that's "do this X number of times with Y character". What is Original Generation's trophy, you ask? Traveling four thousand kilometers with the Cybuster, named "Isolated Lost Child". As expected, you have to get pretty lost while playing as the Cybuster to get this just by playing the Original Generation route.
