School has only been out for summer vacation for three days, and Lucy and Danny are already BORED But their very large dog, Samson, gives them a great idea "Remember when we got him from the shelter?" Lucy says to her brother. "There must be lots more dogs and cats that need to be rescued by now, right?" Agreeing that helping is a good idea, but how? As Danny juggles some apples and a lemon from the fruit bowl into the air, Lucy grabs the lemon in midair. "Mom always says, 'If life gives you lemons, MAKE LEMONADE ' " They high five and shout together: "A lemonade stand " Samson barks his approval. Not only do the kids try to raise money for the Happy Days Pet Shelter, but meet some great characters along the way. Of course, Danny's buddies, Buzz and Clifford, give them a hand by riding their bikes to spread the word. With friends in the media, Roger Radio, Kimberly Karson and Joe Smart to publicize the event, will the kids become celebrities in their hometown of Happy Valley, or will the police shut them down because of all the traffic in their quiet neighborhood? Will they raise enough money to make a difference at the Happy Days Pet Shelter? And what other surprise at the shelter will Lucy find?
