Artoon is the company that made Yoshi's Universal Gravitation and Yoshi's Island DS. Fans were worried that Yoshi's Island DS would be a botched game like Yoshi's Universal Gravitation, which received critical reception, and were upset at Nintendo for going back to Artoon to recreate one of their greatest games in the franchise.^{[citation needed]} However, many fans were happy to see that they did quite a good job on Yoshi's Island DS.^{[citation needed]}
