Sky Jelly Woes, I need a static mesh

Hi, so I am struggling with the sky jellies on my map. The problem is that I want them to be on the ground almost, so that the sky isn’t cluttered, and so they are always available for players to use. So I tried a lot of settings, like the movement factor in the wildlife spawner. A lot of the spawner settings don’t seem to have any effect on sky jellies. I was also messing with the activation distance and spawn timer, to try to keep them close to the ground with a .1 second timer and none of that worked.

Now what I want to do is use a “Health Powerup” With the static mesh of a sky jelly in place of the green heart.

I am kind of new to UEFN, and I’m wondering is this is possible/allowed. I tried to change it to the static mesh and I couldn’t find it, but I know they have like Klombo and stuff on SketchFab.

I just was wondering what actually the right thing to do would be. Thanks!
