The Ice-Cream Machine - Totally Fizzbombed

Twins Wayne and Wendy have two extraordinary friends - an ice-cream van called Macaroni, and a goat called Gina. Then one day they both disappear! Who would steal a bashed-up ice-cream van, and a very naughty goat? Does someone know that Macaroni is actually magical? Hot on the trail of their missing friends, the twins meet Pa Periwinkle - a famous apothecary who once owned Macaroni. The twins need help! Luckily Pa and his magic Fizzbomb Sherbet are soon exploding into action.
