That trick on Peegue Power sounds like quite a mindblower, gotta try that right now.
EDIT: 5810 and 5:06 remaining on Stinky and Loof, Together Again! from WSW. Definitely possible to get 5:07 and 5820 by throwing in a few extra quick switches but I'm not in the mood right now.
You know what bugs me like heck in WSW? No way to show the score for a particular level. It does say "no new record" if you didn't beat it, so it still KEEPS the score, but on the map you can't show it.
