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.
