Hey, I'm trying to do an SMS A-pressless speedrun but I can't figure out how to get past Bianco 3 and Pinna 2 secret. I can't get past the moving platform on Bianco 3 secret and I can't get past the second gap in Pinna 2. Any clues?

For the gap, try using a combination of the hover nozzle, then a dive
