The Marshalls fall into a pocket universe of dinosaurs, Pylons, and Sleestak nightmares that still live in Saturday-morning trauma. Kids' sci-fi with linguists and writers who treated the weird as serious world-building. Foam-and-miniature craft, ambitious for cereal hour, and still stranger than the later joke remake.
