“Little ones...! What have you done!?”

Deep within the heart of your garden, a group of chittering little creatures, designed to clear the leaf liter and cull the weeds with their little mouths, have absolutely ruined the hedges! The long neck grubblies look up at you without any instinct for fear or self preservation, no knowledge, no wisdom. Why would that? That is not their purpose. Your hands can wrap around them easily, and you hold one close.

“Oh no! How did you get into that? You naughty, silly little thing. I need to fix this. The garden must be perfect...”

You can't have the little ones ruining your carefully designed and curated hedges. They are the frame for your masterwork, and you can't have your little ones creating a mess. They already excrete their waste in little holes, breed away from sight, and in all other ways are out of the way. They've just gotten too greedy with the hedges. But you can't just get rid of them; else the leaf litter will pile up. Hmm...

>Change their diet to something else
>Punish this one and hope the rest learn a lesson
