Continuing with your Pokemon-themed series, this should be a straightforward find if you've seen these types of containers before. Use stealth and replace exactly where you found it!
Geodude has been a mainstay of the Pokemon series since its introduction in Generation One. In most games, you won't be able to walk more than ten paces in a cave without bumping into these grumpy fellas. Fans of the show may remember Brock owning one for much of his journeys with Ash. Fun fact: contrary to its name, 50% of the Geodudes you run into on your Pokemon journeys will be female!
