It's a mystery! When 5-year-old Rosalie stops by to show Lulu her brand-new pet, the hamster makes a run for it. Lulu is sure it's somewhere in her house. But if her grandmother finds it before the girls do there's going to be BIG trouble...and poor Rosalie will have to give up the only pet she's ever had. Never fear! There's no mystery too big (or small) for three best friends and their ponies to solve. Lulu's pony, Snow White can sniff out a hamster in a second. But how can the pony help if the hamster is indoors? Snow White may have to go where no pony has gone before.
