Something that I find interesting in all of this Swirly D / Suckerpunch business is that it's initially ambiguous who is speaking after the Clog is defeated, since the voice actor for Sergeant Suckerpunch is the same as the one for Swirly D. Given how there have been other voice actors for other characters it seems that this decision to have the same person voice both Swirly D and Suckerpunch while giving a similar vocal delivery was deliberate. Maybe it wasn't, but I've seen enough people get confused about who is initially speaking in the cutscene after the Clog fight that the similarity between the two voices probably wasn't a developer oversight. After all, Suckerpunch and/or Swirly D could have been voiced by a TTS instead, but they both have the same human actor, with a fairly similar delivery (minus Swirly D sounding more mischievous and nasally - the delivery is most different just before he disappears saying "time to go swirly some nerds").
All in all, even when not considering the plot, it seems like there are some connections between Swirly D and Suckerpunch that Fishlicka put in that are, at least from my point of view, intentional.
