Original Description:
 
After Sonata discovered that toasters for tacos are real, Adagio officially lose the bet they made about it so she has to let her tickle her feet (Sonata’s attempt to lift up her friend’s mood). The taco girl and Aria promised that she wouldn’t have to take off her socks but they didn’t said anything about not cutting them.
 
So how Sonata is using magic? After hearing rumors that Sci-Twilight and Micro Chips were scientifically producing some necklaces to give access to equestrian magic to people who really need it, Sonata made the latter a visit convincing him of giving her one and that she was always a good girl. Sonata is commited to use the magic in emergencies only (apparently).
