Farmer Pickles wants a fence built around his compost heap. JJ sends Trix up to the farm with the materials, and on the way she drops off Molly who is going nature watching. Trix delivers the wood, while Molly finds a family of otters playing in the stream. Trix returns to join Molly, but she noisily scares the otters away. Molly tells her to hide in the undergrowth and stay quiet and the otters will return. But the big, shiny machine is too conspicuous and the otters dart away again. Bob and a very mucky Muck finish their job and on the way home find a miserable Trix. She tells them about the otters, and an excited Muck goes to see. The otters are unaffected by Muck's presence, and Molly realizes this is because the mucky Machine has natural camouflage. Trix and Muck head back to the farm and, with Scruffty's help, Trix covers herself in compost. Now she is able to watch the otters without frightening them, and Muck and Scruffty both have to face to prospect of a good soapy wash.
