Great cute Spike episode. 

Well Rarity's costume was...interesting.  And apparently eight legged dragons are a thing.

I've always wondered if dragons are silicon based, diving into lava, eating gems. But then it doesn't make sense how they can live on carbon based food.

Pee-wee was cute and it was cool for Spike to have a pet. But in the comics Spike eventually returned him to his parents and I guess that part's canon since we never saw Pee-wee again.
