Nagasagy Kikky Park Details
Since Chapter 5 is fresh outta the oven, I see very few talking about this room...
After you knock on the Mike door once, you can knock on it gloobily to have the Mike Trio mistake you for Tenna.
A cutscene plays and then the three Darkners line up in a row for you to interact with. You find this room by walking through the wall behind Pluey.
Here's what I've found so far.
There's a limit to how many dental toys you can add, but you can have an ENORMOUS amount of them before the limit is hit. If you hit the limit, nothing seemingly happens.
If your bomb is called a Kikkybomb, interacting with it will give you an extra cat. Another bomb (a Tiger Bomb) simply explodes your screen for a moment and seemingly does nothing - this one could be found randomly.
If you give a dental toy and then not follow up with another, the Happiness counter will go down.
When the Happiness counter goes below 0, the number turns negative. The cat(s) present will stop moving, start jittering in place, and a continuous meowing will play.
Around the -830 Happiness mark, the stock explosion sound plays and the cat(s) bellies grow bigger.
The more you keep the cat(s) unhappy, the more meowing soundeffects will be added (approx. each new -100 adds more meows). They can overlay atop each other and drown out the BGM.
I've not yet found a limit to how unhappy you can keep the cat(s).
I spent a scary amount of time in this room before actually trying to finish the chapter, but I've not yet seen anything that's significant. It could be a room designed to make theorycrafters go wild like how some minigames had IMAGE_FRIEND.
What else have you found?
