Professor Cypress' Laboratory
Main Article: Garlikid Sidequest
A second Pokémon Professor lives in Rochfale Town: Professor Lily Cypress, a good friend of Professor Bamb'o, who has been experimenting with Pokémon-to-Human speech translation technology. If you pay Lily a visit on your first visit to Rochfale town you'll discover Professor Bamb'o, Lily, and Lily's aid in a frantic mess: a thief has broken into the lab and stolen their Pokémon. Lily will give you a prototype of her Pokémon Speech Translator and urge you and to chase the thief down on Route 6.
This is the the first stage of the Garlikid Sidequest and must be completed to catch Garlikid later in the game.
When you re-visit Professor Cypress' Laboratory in the future, one of her aids will show off another type of experimental technology: a machine that revives fossilized Pokémon. Bring the Tusk or Hair fossil from Comet Cave, and he will revive them into either a Snopach or Slothohm respectively. See Fossil Sidequest for more info.
The Poké Photographer
On the second floor of the house at the very center of town you will find the Poké Photographer. He will give you hints about the Pokémon he wants to photograph and reward you when you bring and show that Pokémon to him.
