Six new My Little Pony books have been confirmed for Spring 2013, with one title implying that the underwater Seaponies could be welcomed back into the Pony community.

The Seaponies were introduced back in 1983 and made few appearances in the years following, but have never been written out of current series My Little Pony: Friendship is Magic.

However, a new illustrated hardback called Under the Sparkling Sea is due in April 2013 and will "introduce fans to a brand new land and an underwater city of Aquastria." Could it be that Friendship is Magic will lead viewers on a visit to Aquastria before the end of season three?

Three other books have been dated for April as well, according to the website for publisher Hachette: Meet the Ponies of Ponyville, Welcome to Equestria, and Twilight Sparkle and the Crystal Heart Spell will be available in paperback and as e-books.

Also in the works are an asyet untitled book due in July, thought to be a Twilight Sparkle sequel, and a My Little Pony handbook called Elements of Harmony, which was first unearthed in September via retailer listings.
