This book tells the story of 11-year-old Audis, who is clumsy and unpopular, nicknamed "Dumbass" by his classmates. He doesn't care, but he's not entirely bothered by it. Unexpectedly, he receives an invitation to the birthday party of Rocco, the class's most popular student, and witnesses a super luxurious and fantastical party. Audis hopes to make new friends at the party, as his only best friend, Jagger, is about to leave to pursue his studies. However, after the party, a series of strange events occur: the scene is a mess, and there's an extra donkey, a sausage balloon, a wedding dress, and many other things, and Jagger is nowhere to be found! Audis, Rocco, Chloe, and others form the "Dumbass Special Agents," carefully searching for clues, discovering the origin of these items, and after a series of incredible events, finally returning everything to its rightful owner. Meanwhile, they solve a theft case, and at the crucial moment, Jagger appears and apprehends Enzo, the burglar disguised as a magician. After these great adventures, Audis became good friends with everyone, and they were all proud to be a member of the "Dumb Agents." Rocco, Chloe, and others also realized that "being brave and being yourself" is a wonderful thing.
