First, Dr. Tooth, your analysis is very helpful in reminding me, when i write my Print on Demand chidrens' books, to make sure my main characters can really interact well with each other. I've got a point here where there are a couple minor characters and it's kind of hard to think how they would do; thankfully, that's not a problem with my majors, I don't think.
Second, regarding the large yellow...oh, count, I'll just let you handle that, you're good at those descriptions!
I wonder why they can't just have Carroll's voice in one.
I mean, this is one of those where it's obvious they could just call him on their cell phones; and especially since Abby gets calls on her cellular wand, even if the others might be deemed too young to have phones.
