Each seven-minute episode is entirely shot in Aardman's distinctive stop-motion animation style. The comedic tone is a combination of slapstick and classic silent comedy, similar to that used in the "Wallace & Gromit" shorts. In this series, there is not much spoken dialogue at all, even from the human characters; simple grunts, bleats, barks, growls, pointing, sighs, mutterings, words, and similar wordless inflections and other animal sounds are all used to indicate each character's moods and motives. There are also no readable words in any episode, although "Bitzer" can be seen on a dog bowl, and—in series four--"Mossy Bottom Farm" on a gate, in the original English-language title sequence. All other signage, such as on a pizza box or a bus stop, is replaced by an illegible scrawl and a picture.
