The underworld of Moanais dark and full of terrors -- one of which we never got to see before now.

In this deleted scene shared exclusively with Mashable, Moana and Maui, the heroes of Disney's latest animated triumph, are lurking around the underworld lair of Tomatoa (the giant crab who has Maui's magical hook).

Along the way they encounter a flock of giant, eight-eyed bats that, in the completed film, are only glimpsed for a quick flyover. But as directors Ron Clements and John Musker explain, a cut-for-time scene showed Moana and Maui using conch shells to trick one of the not-very-friendly-looking critters.

The scene is a part of the extras on the home video release of Moana, which hits Digital HD/3D and Disney Movies Anywhere on Tuesday, and in stores on DVD and Blu-ray discs on March 7.

Additional extras -- and there are a lot of them -- include a mini-movie featuring Moana and Maui, short documentaries on the film's music and cultural heritage advisors, interviews with cast and crew and even a deleted song.

An extra Moanasong? Now we really know how far Disney will go.
