Summary Jess and the puppies find some strange green hairy stuff growing under the water barrel. The puppies are scared of it and Jess promises them that he'll find out what it is at once. Hey, that's the big question! Jess thinks the green hairy stuff might be grass. He goes to ask Baa, who's a grass expert. Baa, Billie and Jess compare the green hairy stuff and ordinary grass using Billie's magnifying glass. It isn't grass but it is a plant. Mimi knows all about plants so they go to ask her about the green hairy stuff. She shows them the green hairy tops of carrots but they aren't like Jess's green hairy stuff either. Mimi's sure she's seen this green hairy stuff in other places around the farm. Jess thinks they should look around and see where it grows. There's green hairy stuff growing all over the farm in cool, damp places. Horace knows all about damp cool places. Perhaps he can help! Horace tells them that the green hairy stuff is a plant called moss and it's not scary at all. The puppies agree. Now that they know what it is they like it! Clever Jess, he's answered the question! Yippety yay!
