"Actually, I've had a better idea" the wicked, dark haired witch sneered at her friendly adversary.
"I've had enough of tormenting this poor creature" she gestured at the snail her most recent spell on Christina had left her unfortunate victim as "I'm going to let you do it instead!"
"I don't know what you mean!" the innocent looking blonde witch replied "I would never torment anyone, and certainly not an innocent stranger"
"No, not deliberately of course. You're far too dull. But let's just say your magic may be misfiring from now on. Try and help Christina all you like, but you'll have very little control over the results" she waved her hand at her opponent and began to walk away "Good luck. This is going to be so entertaining!"
"Hello, Christina is it? I'm Ellie" the busty blond sorceress addressed the snail somewhat awkwardly when the pair were left alone "Sorry about all this. Witches like her give the rest of us a bad name. But I'll get you back to normal and on your way soon enough. Don't worry about that woman's threats, whoever she is she can't disrupt my magic. At least, I don't think so."
And with that she made her first attempt at restoring Christina to humanity.
