As the tiny buzzing creature whirrs around your head. You begin to make out intelligible words in a high pitched cartoony voice.
"You total - bizz- buzz- friggin'--bizz- buzz- teach you---bizz bizz- my toadstool-- buzz bizz--" there was a silent buzzing as it hovered, then it spoke loudly and coldly. "I'll change you into something harmess, a harmless woodland creature, one that doesn't eat toadstools," it said evilly.
You feel a tightness in your throat, your mouth, your butt, your stomach, your crotch, your sinuses -- the tightness is migrating around your body. It feels like your body is sucking into itself. Your eyes bulge, and you belch loudly as your body shrink down so that your shoulder high to the remaining mushrooms or toadstools.
You are still hungry. The green fairy creature flutters just in front of you and over your head laughing at your new form. You hear its cackling words more clearly interspersed with peals of wicked laughter.
"Ha, ha, no prince, but definitely a frog. Not even your mother would kiss you now, ha hahahaha!"
You are still hungry, so you do what you do naturally. Your tongue whips out and wraps around the fairy creature and whip the startled creature into your mouth. It makes a satisfying crunch as you devour it.
You croak, "Harmless woodland creature, my butt!"
