Im very confused on what happened
i think you killed beppi WAY too early; in 1.1 if you kill him too early his head is unreachable
Actually this version of beppi skip (where you go straight to the 3rd phase and the ducks stay on screen) is possible in 1.1. I myself have got it a few times but wasn't recording. It requires ludicrous amounts of damage, where you doing 3 or 4 more doubles after you get the smoke particles in 1.1. I haven't managed to replicate since but i'm sure its there. If you only do a bit more damage in both 1.1 and 1.0 you still get the unreachable head but this requires alot more.
This glitch with the ducks actually happened to me on version 1.3.4. I just used whetstone, super art 3, and charge-spread combo.
