Release the Crackle

So at first when I saw this, I thought, oh thats cute. But then I realized, what if there's a deeper meaning? You know how Twilight is raising Spike? Well it's kinda like that same concept here. Crackle was raised by Luna when she was younger. But the cutest part is, I think the reason she decided to raise such a goofy dragon is because she can relate well with being an outcast.
