This is awesome I'm a huge fan of both doctor who and my little pony, great cross over I hope to see more. I only give 4.5 because Derpy Hooves is actually the official name of the character, In one episode Rainbow Dash calls her Derpy so it's official, unless Derpy was lying so the Doctor didn't know who she was or laugh at her name, in another awesome cross over of ace attorney and MLP Derpy Pinkie Pie told Phoenix Wright, the main character, not to say Derpy's name to her, but then again Pinkie said it so might not be true and it's not official
