No not that one! (・`W´・) I already knew about that! (^ω´ )Happens in NES PRG1 and the game's final cartridge revision for Famicom, too. Appropriately spooky for Boney-kun's debut stage. He can't escape the whip though! No, this was something else!
An Enthralling Story: With VS.C's meaner damage scale, Super Fresh Mummy Bros can't be battled so blithely. I usually fight from the center until one whacks me clear of the pincer, which puts me in position to exploit their sprite overlap = XTREEM DAMAGE glitch for the instakill! "BWAA" says SFMB#1, "HE DEAD NOW" "WAIT NO" says SFMB#2 "OH FUUUCK" say both as BERUMONDO unleashes per-frame annihilation!

But in VS.C, if you've taken so much as a single bump en-route, this strategy is gonna get dangerous!
So I was battling a bit more fiercely in the first phase, and getting PWNED while trying to snap-turn and whip incoming bandages. Turns out the backwards jump I've long been unhealthily obsessed with (check it boyeee ) has a button counterpart! Just like the BJ you need to hit [turn] and the button almost but not quite simultaneously.

As shown it's not easy to trigger, calm down this isn't Holy Diver FFS. But as always on The Hellish Battlefield™, you must verify your shit!
