The tiny creature flies at you angrily. The creature is human-shaped, but it's tiny and moving quickly so you can't tell if it's male of female. Whatever the case you begin to get berated by the tiny thing in a language unknown to you. You attempt to apologize, but you can't get a word in edgewise. You begin to back away, but the creature lands on the ground and fires what looks like a magical rope at you, causing it to wrap around your torso, trapping you arms.
The creature begins to pull. You don't feel as if there is any particular strength to behind the tug, but somehow you are definitely moving towards the ground. It soon dawns on you that you're shrinking. You start try to back up, but you can't move. Within moments you're face to face with the tiny creature. The creature releases the rope, which disappears as suddenly as it appeared. Then the creature (which you now recognize as being female) runs up to you and before you can react and puts something on your head that appears to be some sort of hat. She then wraps her arms around you, pinning your arms to your side.
Soon your body begins to swell slightly, somehow encompassing your arms and your clothes. Your skin looks white, with spots that resemble the color of your clothes. You also feel your feet grow together and round out slightly. The creature smiles and pushes down on your head, causing what used to be your feet to sink easily into the soil.
You try to shake off the odd hat before realizing that you can actually feel its round edges. You struggle to move limbs that you no longer have for a bit before coming to the unavoidable fact, you are a mushroom.
