Ever since Little Fat Bug's birthday, the bugs in the blanket have been great friends. They are such great friends, and have spent so many hours playing together, in fact, that they are beginning to get bored of playing 'hug-a-bug' with each other. And so, at Little Fat Bug's suggestion, the bugs venture out into the garden to find new friends to play with. But will these bugs dare to make friends with creatures they have never seen before?
