Into the Dark Dimension

Prince Highcliff is captured by Hordak during his visit to Brightmoon from his home at Blue Stone. Hordak's shape-shifting assistant False Face assumes the form of Highcliff and enters Brightmoon in order to flood it. He then captures Glimmer and the Moonstone, preventing the Castle from protecting itself - the Horde attack once more and She-Ra and Bow save it.
