What if Cassie, in one episode became giant sized?
It would make sense, in some cases, the smallest of the group in some shows at least once becomes giant. Such as Binky from the Pocket Dragons unintentionally becoming giant when she only wanted to be as tall as Filbert (she didn't put a limitation on the growth potion, and gradually increased in size until the others found the antidote.)
And I know a clever way of Cassie becoming giant sized, since there were flowers that Max and Emmy came across that shrunk them. I think there should be flowers in another place in Dragonland that did the opposite, enlarge who makes contact, which Cassie comes across.
That's something they should have done in the show. A giant Cassie would be a great idea.
Here's the link to an image of giant Cassie I uploaded.
