picture this:
-newt’s little creatures running around in the sleeves and collar of his coat and making him giggle because of soft tiny tickles
-newt laughing his head off and kicking while one of his creatures lays on his chest and licks his neck and ears
-newt growling and being all playful with tina like he is with his animals until he pounces on her and tickles her, later leading to tina doing the same thing to newt
