Paper Koopa Troopa
From the Super Mario Wiki
Paper Koopa Troopas are paper forms of Koopa Troopas that appear as enemies in Mario & Luigi: Paper Jam. Like with their normal counterpart, they attack by hiding in their shell and then firing themselves at one of the heroes. Paper Koopa Troopas are commonly found at Twinsy Tropics and Neo Bowser Castle.
Rare, shiny variants can also appear in place of the regular Paper Koopa Troopas in the same areas. These Koopa Troopas have greater stats and will always drop a Super Mushroom or Shiny Battle Card when defeated, though their methods of attack remain the same. Stronger versions of a shiny Paper Koopa Troopa can also appear alongside Shiny RoboBowser during the battle, which have even greater stats and has a chance of dropping a Double 1-Up Mushroom upon defeat.
