"Ka-doo-doosh-doosh-doosh-doo!"
You can hear Moonie scurring up and down the house as she makes shooting sound effects and so you can't help but laugh a little while you do the dishes.
Since she was turned into a filly, she lost a lot of power and could barely levitate things let alone do anything threatening. As she grows, she regains her power. She's fully capable of levitation and weaponising her bolts of magic. It feels about as painful as a slap but she'll only keep getting stronger. Right now she's managed to regain enough magic to use illusions.
"Hey, Anon!"
You turn to her as she fires a bolt of magic at your face. Instinct kicks in and you raise your arms to shield yourself. You're not sure when, but you spilt some water onto the floor and as a result of your flailing, you slip on the puddle. Because the bolt she fired was just an illusion, your ass is the only thing that receives any injury. You give your ass a gentle rub. This is gonna bruise. Moonie then darts out of the room while cackling at the top of her lungs.
