March

 * 15th March - According to Wikipedia The Eggatons was written by Andrew Ross Hay, and submitted on 15th March 1985. It saw The Sixth Doctor and companion Fay Linden in London in 1926. On an archaeological dig, underneath The Ambassadors Theatre, the Reverend Caden Fry, his old university friend, Brinley Wilmere, and that of his niece, Primrose Darleston, unearth six homicidal creatures literally from beyond the realms of reality. Known as the Eggatons, they are creatures that can give life to any and all inanimate objects in order to aid them with their subsequent invasion. According to the two part script, The Eggatons are a terrifying and deadly alien species, that look like six foot tall ornately designed eggs, on golden tripod pedestals. Each have their own individual swirling array of colour, and to all intense and purpose have the appearance of an oversized Russian Fabergé Egg. They originally come from Cyuram Four, a planet beyond the realms of reality, a world that never really existed but at some point had the potential too. Each Eggaton is therefore capable of literally turning a fantasy into reality, something inanimate into something living. Their shells are imperishable, and their mental capacity goes beyond all other creatures." The Doctor's mind battle with the Eggaton Leader included the Quotrons, Skirkons and Trods who were originally from TV Comic.
