Fuse 8 n' Kate gives picture books the full attention a critic would give a novel, then checks whether they deserve it. The two sisters behind it are Kate and Betsy Bird, the Fuse 8 of the title. Each episode takes its title from a single book, and a run of recent ones shows the range: 'Good Dog, Carl', 'Max's Chocolate Chicken', 'The Red Book', 'Muncha! Muncha! Muncha!', 'Snowmen at Night' and 'Alligator Arrived with Apples'. Detail is what gets the conversations going. In 'Good Dog, Carl' the baby dresses the dog in a jar lid and a necklace, a look Carl pulls off, and then falls two stories down a laundry chute. The sisters react with mock alarm and a pointed question about why anyone let the baby near it. 'Max's Chocolate Chicken' becomes an argument about Ruby and why a character so clearly out to win bothers to push Max into competing. One sister thinks Ruby just wants a real contest. The other suggests she wants to see Max cry. 'The Red Book' gets a continuity check: if two children are looking at each other through their books, why is one of those books shown closed? Word choice matters too. With 'Muncha! Muncha! Muncha!' they follow a man's temper as it climbs from angry to really angry to furious with each round of gnawed sprouts. They call that build the thing that makes it a good read-aloud, then debate whether a word like 'irritated' would have taught children more or just been less fun to say. 'Snowmen at Night' gets a mock-serious look at how snowmen would actually race down a sledding hill, plus a tip to search the gaps between them on the racing page for hidden pictures. Around the books there is plenty of sibling nonsense. One episode starts with a string of absurd guesses, running from a number to a tomato to the Constitution, before the question has even been asked. In another, Betsy pats herself on the back and thanks herself by name, playing both sides of the exchange. Scores are part of the format, and the sisters remember them. Kate once tallied the six so-called Thanksgiving books Betsy has handed her since 2017, starting with 'Cloudy with a Chance of Meatballs', and quizzed her on which rated highest. The answer was 'Green Eggs and Ham', with an eight, and Betsy admitted her theme had mostly been food. Letters usually come at the end, though one episode moves a letter to the top. Even the closing credits join in, listing the same person under a new joke title each time, such as 'our good boy' and 'our chocolate chicken'. The jokes do as much work here as the verdicts.
