Zaggar-Six was a planet which the Fourth Doctor visited at some point in its history.
The Doctor hadn't eaten anything between leaving that world and arriving at an English village that was being attacked by General Ironicus' Iron Legion. He tried to buy provisions, as well as some jelly babies, at J. Grubb General Store with some Zaggan pound notes which, according to him, were "a little on the slimy side, but absolutely inflation-proof!" (COMIC: Doctor Who and the Iron Legion)
