Shadow Demons

The Shadow Demons are evil demons who helped Doctor Facilier in his evil plan to take over New Orleans. In the film the demons help Facilier as long as he keeps his promise to give them the souls of New Orleans residents. When Facilier is unable to pay his debt the demons kill Facilier once and for all.

The Princess and the Frog
Thanks to his bumbling sidekick Lawrence, frog Naveen has escaped leaving Facilier to ask for help from his friends. They grant him Shadow Demons to obey his every demand and capture Naveen. They head off into the Bayou and find pieces of a balloon with Naveen's scent. They begin to head back to their dark master until they are destroyed by Mama Odie. Later on when Tiana and the other head back to New Orleans, the demons are able to capture Naveen. Back at the city, Naveen escapes yet again and manages to give Ray the firefly the talisman used for Facilier's plan resulting into the demons resuming their work. They are halted by Ray who battles the demons with ease until he is killed by Facilier. The other demons follow Tiana who now has the talisman but she soon destroys it. The demons then turn on Facilier and drag him into the voodoo world from which they originate from.

Trivia

 * One of the masks, a large, pink and green mask with long black horns that face downward, seems to bee the leader of the demons, as the others look to it for guidance and approval. The mask also serves as a portal to the "Other Side", which is believed to be Hell. It provides Doctor Facilier with his voodoo hayacall, it releases the Shadow Demons from its mouth, and it sucks Facilier inside it when the hayacall is destroyed.
 * One of the Shadow Demons summoned by Facilier is tall, skinny, and has large, oval shaped eyes, leading many to believe that this is supposed to look like Jack Skellington.
