So the skill needed is kinda hard. I saw that flowers have the same physics as SMG2 clouds so if we time well we can jump on it.
At the 2nd hour of tryhard I managed to get to the big flower with a backflip from one of the last fountains, but I couldn't manage to reach the stars after that.
Near 2&1/2 and the 3rd hour I discovered that flowers are a reliable ground for triple jumping. I then theorized the idea of making the 3rd jump on the big flower to reach the launch star.
At the start of the 3rd hour I theorized that you could use the fountain in the back (the last I touch on the video) to then jump off the flower to start a double jump which possibly leads to the triple jump I needed.
~15 minutes after that, I triggered the hitbox of the big flower with only a double jump (and trust me, getting to trigger the big flower like that is an achievement. And getting the triple jump off of it is ridiculously hard)
~15 minutes before my last attempt I managed to pull off my 1st Triple Jump, unfortunaltely I missed the launch star
Finally, my last attempt (The 2nd time I pulled off the Triple Jump) went well *and that's how I managed to get the "GG you became a Bee" on the climbing/queen planet*
