Chase, despite having worked in the garden for a few months to earn a bit of extra cash, doesn't know a whole lot about plants. If it needs planting, dig a hole, if it's in the wrong place, move it, if it's too big, chop it off.
What he does know, is that these white things going around are not plants.
He jots down a note for Asar-Suti and leaves it at the bar.
Boss,
I don't know if you've seen but there's some sort of space slug invasion in the garden. Are they meant to be there? If not, what do you want doing with them?
Chase.
Then he goes out with a wheelbarrow and a net to try and catch a few, because he can always let them go again. This doesn't seem to be going well.
