Letty and Oz are trying to figure out why this norn looks kind of like a dog. The reason is, actually, that the norn's mom IS a dog.
See, Oz's ship crashed into the old, disused playground of an abandoned schoolhouse. He couldn't fix the ship so he cloaked it and made a hologram of a tall wall all around the school. Animals cant see the hologram, though, so they wander in all the time. When the ship crashed, the glass on the terrariums shattered, so norns wander around the playground and school.
Some norn male fell in love with a dog girly. They're so cuuuuute. o3o anyways, this is their baby. this is the parents. [link]
Oz and letty are confused. D:
And yes, Oz does need reading glasses. Like the tenth Doctor.
