I think I need to put a bubble and blink thru it before blinking to the white button in the north
but I don't know yet where I need to blink to in the bubble.
Yes, that's right. Think back of the Abandoned Fort. Then I got it!!
It doesn't matter where you end up as long as it's somewhere you can stand. As long as you get to the white button before it floings you back you'l be fine.
You only need 3 to get there and 3 to get back so you should have plenty left. If you place one diagonally to the left at the start you can walk round diagonally most of the way, then place another one diagonally when you get to the 3 in a sort of V shape, then you need one for the next gap before the bridge. Don't forget to brr behind you at each stage or you won't get back after you've got the pow glove. I placed the brr to get the coin before I got the pow glove, but didn't get the coin until I'd used the pow glove to kill the ice flower, then I was in no danger bouncing back.
If you still can't understand it I'll floing back and do you a screenshot.
When u get the time, u might want to do that. I started out diagonally, but I'm getting stuck after the first 2. I'm gonna go have a look see again, but that is what I figured I had to do, and I got stuck.
