#3 gets my vote for stating specific examples, helping to give a clear picture of Gabby and her predicament. ht
The “Gabby has a lot to say ...” pitch seems more kid-friendly and shares the essence of her problem without being too wordy or detached. I can glean quite a bit about Gabby and her personality from these few lines!
I like 2 because it give more information and isn't as vague as the others.
