Why

In a turn-based battle from a pixel-art role-playing game, the character Erk, a red-robed mage, casts a spell on Serra, a pink-robed mage, causing her to transform into a chicken-like creature. The scene loops, showing the transformation, a brief cut to a close-up of the transformed Erk with the text "NUUUUU," and then returning to the battle screen where Erk's health decreases while Serra's remains full.
