Earlier this summer, Nickelodeon announced the arrival of Middlemost Post, the cable network's first original animated series in five years. Now, the show's catchy opening song has been released, and we're debuting it exclusively on CBR.

Composed by Matt and Tish Mahaffey, the theme song sets up the premise of the series which stars Angus, a former boat captain, and his partner, a former rain cloud named Parker J. Cloud. The duo, joined by their pet walrus, are tasked with delivering packages for the residents of Mount Middlemost as the owner and employee of the titular Middlemost Post.

The Middlemost Post theme song will be included on Nickelodeon's upcoming Mega Music Fest Album, set to be released on July 16. The 10-track album will be available on all major streaming platforms. The album will include tunes from other shows, including The Loud House, Tyler Perry's Young Dylan, The Casagrandes, Side Hustle and more.

Middlemost Post was created by SpongeBob SquarePants alum John Trabbic III and features the vocal talents of Becky Robinson as Parker J. Cloud and John DiMaggio as Angus Roy Shackleton, Parker's boss and the owner of the Middlemost Post.

Nickelodeon's Middlemost Post premieres Friday, July 9 at 7:30 p.m. ET/PT. New episodes will air every Friday after that.
