chunk: As Jarvis and Tweel approach a city on the canal bank, they are passed by a barrel-like creature with four legs, four arms, and a circle of eyes around its waist. The barrel creature is pushing an empty, coppery cart; it pays no attention to Jarvis and Tweel as it goes by them. Another goes by, then a third. Jarvis stands in front of the third, which stops. Jarvis says, "We are friends," and the cart creature repeats the phrase from a diaphragm atop its body, "We are v-r-r-riends," before pushing past him. The next cart creature repeats the phrase as it goes by, and the next.
  Eventually the cart creatures start returning to the city with their carts full of stones, sand, and chunks of rubbery plants. Jarvis stands in front of one and refuses to move. The cart creature tweaks his nose hard enough to make him jump aside and yell "Ouch". After that, every cart creature that passes by says "We are v-r-r-riends! Ouch!"
