You're peacefully washing dishes in the shared home of you and your dear Kajii. Sure, he's psychotic and maybe even a bit insane, but he's just a little guy! It's not his fault! If making lemon bombs and wreaking havoc is his favorite activity, who are you to stop him? At least that's what you tell yourself.
CRASH!
It's also what you tell yourself when you hear the booms and crashes of his experiments. Clearly, it's time for zoomies. At least once a day, Kajii has about an hour or two of being purely insane and running around like a toddler on a sugar high. It's a bit scary if he has his chemicals and science equipment with him, but usually he's just running around.
“BAHAHAHAHAHAHAAAAAA!!!”
Or making things blow up, outside of course. You hear him doing it now. He begins to laugh manically while countless loud noises echo. You chuckle in endearment at his antics and wait until he either comes inside to drag you into it, or until he crashes on the couch from exhaustion. It’s all just normal zoomies for you.
