Voltron: Defender of the Universe - Season 1, Episode 19

Trailer

Three children discover an unknown castle and choose to look for riches within. Pidge, interested by Coran's story of a similar fortress that held wealth until it was buried so no more wars could be fought among those trying to take its contents, flies out himself and joins the group. Nobody knows it is the work of Haggar's magic until they are trapped in the bell-tower, and the rest of the Voltron Force follow only to be confronted with indestructible fighters - and ships to tow the foundation off when all but Keith are imprisoned as well.
