Animal Magic (series)
From Tardis Wiki, the free Doctor Who reference
Animal Magic (series) was a BBC children's television series which ran from 1962 to 1983. In an appearance on the show, Tom Baker, in character as the Fourth Doctor, recounts some of the "animals" he has met on his travels.: the Shrivenzale, the Krynoid, the Wirrn and the Fendahl. This particular clip was re-released on the DVD of The Creature from the Pit as it was during this filming of that serial that the clip was produced.
