As of my last knowledge update in March 2023, "Orange Hippo!" is not an individual author, but rather a book series brand published by Welbeck Publishing. This brand is known for creating small-format gift books that cover a wide range of topics, often delivering content that is humorous, informative, or inspirational. Their books often feature quirky facts or motivational quotes and are designed to be easily consumable, making them suitable as gifts or light reading material. If "Orange Hippo!" has since become known as an individual author, I would recommend checking more current sources for updated information.
