Paper Fuzzies are paper forms of Fuzzies that appear as enemies in Mario & Luigi: Paper Jam. Their appearance is based on the modern Fuzzy design rather than their design from the Paper Mario series. One of their attacks involves two of them bouncing on either side of one of the bros., and then jumping at him, which must be dodged by jumping in order to avoid damage. Paper Fuzzies can also attack by jumping in front of the bros., and must be hammered in order to stop them from attacking. When it takes damage, a Paper Fuzzy splits into two smaller ones, and attacking the Fuzzy again results in the enemy splitting into two even smaller Paper Fuzzies. When attacked a third time, the Fuzzies become a Fuzzy Horde, forcing the trio to run away. If the bros. successfully run from the Fuzzy Horde, it flees from battle. Paper Fuzzies are found behind a building in Mount Brrr during the Paper Toad Freeze-Out, and stronger variants are found during the Final Smash mission in Neo Bowser Castle.
Paper Fuzzies can also be seen if the bros. have defeated a Chain Chomp-wielding Shy Guy in Neo Bowser Castle and an enemy is still on the field. The Paper Fuzzy comes from the left or right side of the screen, followed by a Chain Chomp or Paper Chain Chomp. They can be stomped on to deal damage, though they cannot be defeated. They may also come out of a barrel thrown by a Paper Broozer, and may randomly appear in the background afterwards.
Rare, shiny variants can also appear in place of the regular Paper Fuzzies in the same areas with greater stats. The ones in Mount Brrr always drop either a Supersyrup Jar or a 1-Up Mushroom, and the ones in Neo Bowser Castle always drop either a Max Nut or a Double 1-Up Mushroom. The shiny variants in Neo Bowser Castle are at level 49, the highest in the game.
