A Doctor Whooves fanfic. Inspired by Lissy-Strata's artwork. The Master has taken on the inexplicably brilliant yet socially awkward Derpy Hooves as an assistant. As much as she annoys him, she is particularly useful. Especially when she accidentally swallows the TCE, giving her hiccups a rather amusing power. Amusing to everypony but the third Doctor, that is.

Many, many ponies come to live in Ponyville rather suddenly.
