In what is definitely a fable for our times, a young billy goat finds a lost cell phone and, with a friend, proceeds to take selfies and make prank calls to sibs. But when they find Troll's phone number, they then troll the troll with a series of bullying texts in a clever bit of role reversal ("GET OFF THE BRIDGE!" "YOU STINK!" "A MOOSE LOOKS LIKE YOUR MUM"). In the cartoon illustrations, Troll is envisioned as a hideous, hairy green monster, but when the goats reach its lair, all they find is a tiny, tearful minitroll. "Why do you hate me so?" she sobs. "Not every troll eats goats, you know." The remorseful goats put the phone away and proceed to "play a game called Making Friends / which everyone should play." Readers primed for a sudden, crunchy resolution, like those found in previous Willis and Ross collaborations (Tadpole's Promise, 2005; Fly, Chick, Fly!, 2012) may be disappointed, but the episode should spark some discussion of empathy and unintended consequences.

Billy Goat finds the farmer's lost cell phone and--with his best friend, Cyril--takes selfies, makes prank calls, and cyberbullies a troll. The goats only learn half a lesson: they eventually befriend the tiny troll they bullied but suffer no consequence for keeping lost property as their own. Forced rhymes create an unnatural cadence, but Ross's entertaining illustrations are lively and expressive.

Kirkus Reviews

Two kids—as in young goats—prove just why that creature has a tough reputation.Little Billy finds a cellphone in a field, "like the one the farmer lost"; said farmer is scouring the tall grass a few feet away. Billy "kept it for his own." Strike one. Hiding it from his folks, he teams up with his friend Cyril and, after a little minor mischief, Billy suggests "Let's make a funny call!" Billy's brother gets a burp; Cyril's sister gets a "whooping like a big baboon." OK, they are on thin ice but still dry. Then they discover Troll's number in the contacts. "Oh, what a laugh, yippee!" Since they are afraid of Troll, they text. "Get off the bridge! You stink!" Whoa! Strike two. Still laughing, Billy says, "I bet Troll's got an ugly mug— / let's take its photograph!" So now a little B & E into Troll's cave. Strike three. There they find a baby troll, crying as a result of the prank calls (illegal in most states, considered harassment, stalking, or bullying: strike four). The kids apologize, though even Ross' soft colors and easy linework fail to convey much remorse when they "hung their heads in shame." Then they all make friends. Forgiveness is a beautiful quality, yes. But the kids are more delinquents than pranksters, and with "friends" like them.... Let's be honest. The goats are the stinkers. (Picture book. 4-8)

K-Gr 4Two goat kids, Billy and Cyril, find themselves in possession of the farmer's lost cell phone. In rhyming prose, the author takes readers along as the two friends make mischief with the cell phone. First, they take pictures and film videos of their fellow animals. Billy and Cyril undress the poor scarecrow and take selfies of themselves in his clothes. Next, they make crank calls to people on the farmer's contact list. The naughty goat kids are delighted with themselves and their antics. When they discover the contact information for the troll who lives under the bridge, they get an idea. Having heard from Grandpa Gruff that trolls will eat them, Billy and Cyril text the troll numerous times, telling him that he stinks, that he should get off the bridge, and that he is dumb. Next, they decide to take a picture of the troll, put it on the Internet, and caption it, "The foulest face you'll see!" The two billy goats go into the troll's cave intending to take a quick picture and get out before being eaten. To their surprise, they do not find a terrifying creature, but a small, crying troll. Someone has been saying mean things about her. The goats admit to the pranks. Troll cannot understand why they would be so mean to hershe has never hurt anyone, and trolls have feelings, too. The goats are ashamed and ask her forgiveness and make friends with her. One cannot miss the "bully goat" reference or that this is a moral-of-the-story book. However, this title presents the timely issue of cyberbullying in an age-appropriate manner. The billy goats wear clothing and live in a house with their parents, making them seem just like average "kids." The tale is not too wordy and works well with the illustrations. The bright watercolors are engaging, with just the right amount of fun to hold the attention of most children. VERDICT A worthy addition to social emotional learning collections and to storytime read-aloud lists.Mindy Hiatt, Salt Lake County Library Services
