Super Flag Achievements

There are eight Achievements you can achieve in this game. They can be achieved at any time, and through a number of conditions. However, it is worth noting that, after completing World 1-6 and getting the first Royal Sticker, there are eight Super Flags in the Sticker Fest area of Decalburg. You can examine them to check on your progress to the Achievements.

 

 

 

 

Luigi Locations

In the background of certain levels, you can spot Mario's brother Luigi, who can be peeled off the level by Paperizing. If you peel him off in all 5 locations, he'll appear during the credits sequence. In addition, each individual peeling will unlock a rather amusing newspaper article in the leftmost house in Decalburg's Residential Area.
