I gave up on >>274752714 's Playroom one because I just wasn't enjoying trying to move shit (>buys physics game >doesn't like physics), but for yours with the three platforms, just brute force it. Hold the button down until the platforms hit the right wall, and as soon as you let go you gotta start running to do some Mario hops. It took a few tries and even on the one when I succeeded it was 'cause I was hanging onto the pipe edge by an armpit, flailing with my other hand to try and force grab the prize.
FYI that one contains [spoiler]one of the gacha egg things that I believe unlocks whatever enemy type that is for use in the Sandbox mode later. I also think you need to carry the egg/toy/whatever in one of your item slots all the way to the Reclamation Bin at the end of the level, which is still a ways away. So, have fun.[/spoiler]
