On Sunday, Mr. Jenkins welcomes one pig into his pool (as a guest of his neighbor Ms. Peal, who's brought along her famous seven layer dip as well). Really, how much trouble could one little pig be? But one pig becomes two and two become four... And by Saturday there are just TOO MANY PIGS IN THE POOL! This funny story will have readers laughing along with pigs Percy and Wanda while also learning about multiplication.
