Following on from the excellent "Chicken Clicking" about getting carried away online, this twist on the everyday child story is just as wonderful. Here a goat finds a mobile phone, does some goofy things with a mate, and then trolls - well, a troll. Who turns out to not be the routine bridge-demonising, hungry troll after all. Sticking to a great rhyme, twisting the relationship between the troll and the goat (and of course twisting Internet terminology so it's the goats doing the trolling) - all about this is spot on; and another abject lesson in showing how books with a Serious Purpose can be thoroughly entertaining with it.
