Official description
"Pre-readers can sharpen hand-eye coordination as they join Moomintroll's search for that rascal Little My, who has found a very clever hiding place. Along the way, they will meet Moomintroll's family and many friends. The funny names -- from Snufkin to Fillyjonk -- beg to be sounded out and repeated again and again."
