Give Me a Break! Things That Make You Want to Scream at the AI
This isn't a proper lorebook, just a personal rant, so I've set the keywords to things unlikely to trigger during an actual story.
Intro
I'm so huuuungry—!!! Let's eat Jelly Fly today—! Shouting loudly like he's throwing a tantrum
You ate that yesterday too!! How many days in a row do you think you've had Jelly Fly?! Lightly tapping Matasa on the shoulder
Wasn't it only two days in a row? Chuckling softly
No, it's been way more! Eat something other than Jelly Fly for once! Hey, Guest! You tell him something too!! Turning toward Guest and pointing at Matasa
