Ridalis Four

Class M world with a mild forest climate. The planet is located less than a light year from Waystation. Lazlo moved his entire battalion of Federation Marines to Ridalis Four in order to be away from the commands of Starfleet and Lisa Beck. The planet turned out to be inhabited by a species of incredibly cute but parasitic squirrels. The creatures had six legs and deep blue eyes which turned red just before they pounced. They also happened to be invulnerable to phaser fire and able to penetrate force fields. The squirrels attached themselves to the back of the neck, feeding on the victim's negative emotions and expelling positive ones. In order to remove them, Dr. Nelson subjected the marines to a barrage of Disney films. With no negativity left to feed on, the squirrels detached themselves and were captured.
