 The rangers have a huge test to prepare for so they go to some cabins in the mountains that Billy s uncle owns to study with no distractions. Bulk and Skull go along without the rangers knowing so that they can cheat off of them. Goldar uses the Crystal of Nightmares on the rangers and Bulk and Skull that make them lose their confidence in themselves. The now frightened rangers refuse to fight ever again and are further disheartened when Zordon tells them that the only way to free themselves of the spell is to destroy the crystal.
