Llama Llama is invited to Grandma and Grandpa's house! And it will be his first night away from home . . . and from Mama. He packs everything he needs and soon he's having fun with Grandpa and Grandma Llama, riding their lawn tractor, helping Grandpa in his workshop, and eating a "different" but delicious dinner. But when Llama Llama goes to unpack his overnight bag, he realizes that he's forgotten a very important item ⁠— Fuzzy Llama is not there!! Suddenly, Llama Llama is very homesick. But Grandpa knows just what to do. He fetches his own special toy from when he was a boy and helps Llama Llama see that he's not alone; he's safe and loved in Grandma and Grandpa's house, too.
