Under the Mountain - The Alien World Below (Episode Four)

Classic sci-fi series Under the Mountain follows redheaded twins with psychic powers — Rachel and Theo — as they battle the alien Wilberforces. This fourth episode sees the twins venture into the aliens' submarine lair for the first time. The lair's moody production design, the NZ Symphony Orchestra's score, and creepy transmogrifying special effects contributed to the slimy imprint the series left on a generation of Kiwi kids, haunted by the giant slugs slithering underneath Auckland's volcanoes. The award-winning series was adapted from the Maurice Gee novel.

What were those things?

– Theo (Lance Warren), after first sighting the aliens in slug mode
