OK. This is a few update from me.
About the punnies disappearing problem, i found a little gap. Each time you blow punnies with Flurrie ability - you have approximately 4-5 seconds before they disappear. So when Mario trapped in a cage with punnies and need to release them (this case, you already have super boots), make sure before you blew them down the hole, you are standing close enough to punny orb square light - so when the punnies go through the hole, your punnies counter will calculate, that means Mario already release them.
Just like I said before - you only have approximately 4-5 seconds before they disappear, so what you must do is blew them (1 second or less) and then quick pick them up, go back to the cage through the pipe, blew the rest, and pick them, repeat this move till you release all the punnies.
This trick works for me. And I'm using Dolphin 2.0 for this trick.
