Jitters

Jitters is one of two named radroaches caged in the sniper shack in 2277. It is locked in a cage, together with Fluffy.

Other interactions

 * If released, it will attack the player character seeing as both radroaches are hostile from the get-go. After they are released one can get them into their cage again by standing on the cage with the door open so they will follow the player character inside their cage.
 * Unlike most named creatures, they will respawn if they are killed.
 * If one gets too close to the cage, the radroaches can attack through the cage bars and deal damage.
