S8, E10: When Sarah and James get a new pet guinea pig from their uncle, Fireman Sam, it doesn’t take long for it to escape. Fortunately Elvis is on hand – along with the Thermal Imaging Camera and a box of fire station equipment – to try to help them find it. But in the meantime the guinea pig has managed to chew through some electrical cables, starting a fire in the Wholefish Café. Sam and Penny soon put out the fire, and Elvis confesses to Steele that he was using all the equipment to find a guinea pig. Steele is dismayed, there’s only one way to find a guinea pig – tempt it out with some sunflower seeds. It turns out that Steele has a soft spot for guinea pigs, especially this one, as Sarah and James have named him Norris – Steele’s first name.
