On March 25, 2021, Dav Pilkey announced on his YouTube channel that he and Scholastic will cease further publication of the book "The Adventures of Ook and Gluk," and will remove it from retailers and libraries due to some racial stereotyping of the characters in the book even though the Asian characters are the heroes of the story. Pilkey stated that he intended to showcase diversity, equality and non-violent conflict resolution. He also stated that even unintentional and passive stereotypes are harmful to everyone. Pilkey will donate his entire advance, past and future royalties from the book to organizations promoting diversity and designed to stop violence against Asians.
