The Talking Pig Book 1 of 3 Books is a story about UTU and Oink Oink, one little pig that is much smaller than his brothers and sisters.
"Utu and Oink Oink lived together for a long time. They laughed and played together. Utu's teacher never let Oink Oink into the classroom, but he talked loudly so that the pig sitting outside could learn. Utu's mother never let the pig into the garden, but she gave him lots of food to eat. Utu and Oink Oink were best friends, and had many adventures."
