As with all Pokémon games there are a handful of useful characters dotted throughout the map. Here's how to find them and what they can do for you.

Name Rater

Location: Lavender Town

This eccentric fellow lives south of the Volunteer House and will at no cost judge your Pokémon's nicknames. If they belong to you he'll even let you rename them.

Happiness Checker

Location: Pallet Town

Your rival's sister who gives you a Town Map the first time you meet her. She lives next door to you. If you visit her later on, she'll groom your Pokémon from time to time thus increasing its happiness. She will also give you notes on how much your Pokémon likes you
