Capture 20 Sqvips
Sqvips are small orange squirrel-like animals & purple rodent-like animals that can be caught during the game. You will encounter them first during one of the main quests before facing the Jumbo Puff world eater. You will first obtain them in an area in the Deadzone for the main quest, but they can be found all over the game world with no specific set spawn location.
When you see one approach it and press Y (interact) to catch it, then you are given a choice of whether to kill the animal or capture it, which awards an Aura point depending on what you pick.
Catch 20 total of these (regardless of what Aura choice you pick) to earn this achievement.
