This is done in the "Glimmerdimm Beach" chapter.
As you make your way through the start of this section, you'll be introduced to some jelly-like jump pads that will boost you up into the air when you land on them. Once you see a very large one (you'll jump off a short cliff onto it) and it'll toss you up to a smaller green one. Just after the green one is an archway that you'll pass under (there's a slide immediately after so be careful as you approach it). You need to use the green jelly booster to rocket yourself into the air so you land on the archway. A normal jump won't get you up there, but if you use your slam ability (
+
), you'll slam down on it with enough force to send you flying up in the air. Use your second double jump (
) and your float ability (
) if need be to get the rest of the way up. As soon as you land on the archway, wait about a second or two and the trophy will pop.
