I want the Chibi 2759 but I got the common 2759. Can I use a Chibi potion on her and get Chibi 2759 or do I have to keep zapping to get the chibi version?

You can definitely use the chibi potion to turn a common to a chibi one.

You would just have to use a Chibi Potion! That's what I did for Strikeur when I finally zapped him into a 625. Congrats by the way!

Awesome! Thanks so much :)
