(Recently there was a quest added where you are teleported somewhere and have to find a bunch of little creatures by clicking them in the background of the street... Click here to see the quest!)
I was thinking something like this could be a fun addition to the main game overall!
Each street could have the chance of spawning a special & untradeable (Meaning this would be the only way of obtaining them) uncommon or rare item, in its background. You would have to find it and click it to obtain it.
(One type of item I was thinking of that you could find would be decorations for our homes, towers & home streets.)
Picture Example: Click!
Example:
1. You are strolling along through different streets. Suddenly you spot something unusual in the background! You click it with your cursor.
2. Its a rare (Or uncommon) item! Its put into your inventory.
Achievement Picture Example: Click me!
Achievement Example:
Like many other achievements, you can acquire achievements for finding a certain number of hidden items! For the picture example I chose finding 41 hidden items.
This achievement would likely be found in the Exploring category.
