Lil Dicky dropped the video for “Earth,” his animated video for Earth Day that features a host of celebrities, including Ariana Grande, Justin Bieber, Halsey, Bad Bunny, PSY, Zac Brown, Miley Cyrus, Sia, and Snoop Dogg.

Aside from Lil Dicky, Leonardo DiCaprio is the only celebrity depicted as a human in the video, and everyone else is an animal.  Lil Dicky spoke to Time about the video, explaining:

“It really kind of started out as, ‘I love animals. I’d love to make a song where different artists play the role of different animals.’ What started as a silly joke of an idea along the way became the most important thing I’ll ever do.”
