Good for the new Mother that there is an empty house just down the street. ;)
You don´t want to fly anymore, so you decide to look for something suitable. Just then you see a girl walking down the street.
You work your magic so she walks in an empty Park nearby so nobody will notice her changes.
She was just walking home from a friend when she notice she´s in a Park. "That´s not the way home", she thinks. "Why am I here?"
Just when she stops walking to turn around her full Body start to hurt very badly.
She falls frontward and try to stop the fall with her hands when she realizing, that she no more has any hands but hoofs like a Horse.
Her Body stops hurting and she look back only to see that she really is a horse now and her clothes became a saddle and bridle. Her fur is snow-withe with not one dark spot on it.
Just a moment later her Skull starts to hurt really bad but she manage to look up to it when it forms a horn on top of it.Its about 3 and a half foot long when it stops to grow.
Finally there is a short pain on her sides when a pair of large feathered wings burst out with a span width of about 70 foot.
After the changes are done you see that your new horse is about to panic, so you quickly gave it a new mind of an obedient and loyal horse - the original is still intact but under the new one, of course - and shrink it down to a side you could use.
At last you sit happily on it - it seems happy to have you on it´s back - and flying through the air with it.
