The McTavishes have piled into their old rattlebang car for a picnic on the top of Mount Fogg. But when the mountain starts to shake and red-hot lava erupts, the McTavishes hope that the old rattlebang can stay together long enough to save them from disaster! An original tall tale with an outrageously bizarre plot[Mahy's] writing is vivid, funny, and full of details that will be dear to a child's heart. -- School Library Journal, starred review
