The Secret World Of Posh Pets, 8pm, ITV

THE final episode meets a young man (Rory, pictured) who is making his fortune selling what must surely be one of the most bizarre arre pet choices imaginable — jellyfish. Yes, jellyfish, which he exports around the world. Plus, the growing market for blinged-up horses, with unicorn horns, sparkly hooves and glittery stars on their manes.
