|One Big Unicorn|
One Big Unicorn is the puppet book written by Gru. It reflects on the story of Gru's life. He writes this book because Kyle ate the girls' favourite bedtime storybook, "Three Sleepy Kittens". He wants to show Margo, Edith and Agnes how much they have helped him, though he does not want to admit it, and claims that the girls have nothing to do with the making of One Big Unicorn.
