An experiment, huh... [Ren looks deeply thoughtful about that, meaning he's pouting deeply and doesn't actually look like he's thinking all that hard, just wearing a really exaggerated version of a thoughtful look. Then, rather suddenly, he looks quite delighted and snaps his fingers.]

Oh, maybe they're trying to figure out ways they can make us breathe petals too! [As if on cue, the petal-breathing slime leaps up onto Ren's shoulder and starts sending out a veritable blizzard of the things, which only seems to make him look even happier about the whole absurd situation.]

And other things too, I guess, but petals are more interesting.
