Telltale

Telltales are particular NPCs found in certain places who can send you on special quests where you fight tougher bosses and stronger versions of enemies. These quests are repeatable and you can get a lot of XP and Caps from them, but it's the main way to get Cute Little Puppets, which can enable your access to special places like Pomona. You also get some other random rewards after completing a Telltale quest.
