Summary: The Fart Powder was such a successful invention that Doctor Proctor, Nilly, and Lisa couldn't stop there. Next up: a time-traveling bathtub. You just hop in, lather up the Time Soap, and wish for where you'd like to go! Doctor Proctor has plans for this new invention: He's going to change the course of history and keep his true love from marrying an evil count. But when things go wrong, it's up to Nilly and Lisa to travel back in time to reunite the two lovebirds. Enter a herd of hippos, a scheming assistant, Time Soap that keeps going awry - Nilly and Lisa end up at the storming of the Bastille - and things have gotten beyond complicated! Fortunately, the fart powder solves everything. (Publisher) Also published as: Time-travel bath bomb Translated from the Norwegian Doctor Proctor's fart powder
