Romero

Romero is an NPC related to the Romero and Juliette quest, where the player assists him in getting presents for Juliette.

Quest
To make Romero appear, you must first talk to Juliette. Every step of the quest Romero's will change location.

Trivia

 * Both Romero and Juliette are a reference to the main characters in the play Romeo and Juliet by William Shakespeare.
 * His outfit is likely a reference to Where's Wally/Waldo? (who wears a red and white striped hat and shirt, glasses, and blue pants), and the fact you have to find Romero after every stage of his quest is also likely a reference (even if the method you find him is different than in the puzzle books).
