Friendly Monsters
The friendly monster side quest involves locating several creatures around the world map in the forested areas.
You can find each of them in any order that you prefer. However, you cannot find the last Friendly Monster (Yan) until you have found all 8 of the other monsters. Finding Yan before you have found the others will cause it to run away.
When you encounter one of the friendly monsters listed below, it will ask you for an item of some type. You will have to select the “Item” command and ‘use’ the item on the monster.
Mister Nice Guy
Achievement/Trophy
You need to befriend each of the Friendly Creatures in the game to obtain the
