You can add the character: Mr.Painter? (Made by me), when you have close of Mr.Painter, He throw paint in your face, so you have paint in your face for 20 seconds (is black)
Mr Painter is a Art Teacher

I'm very bad for draw in PC...
When Mr Painter throw paint in your face, he's say: "LOOK, it's orginal art, your art hater!" or "My art is cool, you don't like? TAKE THIS IN YOUR FACE
Your cooldown to throw paint in your face is: 25 sec.
When he's idle: "Huh, where's my students? I want my students to see my art!" or "Anyone saying for me 'The GUY don't like your art', where's the GUY?! "
He can enter in rooms
When he see player, he's say: "OH, YOU ARE THE 'GUY'! COME BACK HERE!!"
When he lost the player: "What?!! Where are you?? Nooo!"
I don't know how to make the voice of Mr Painter, so you can make, He will stutter and speak a little in a thick voice, not so thick , right? :)
