Paper Scaredy Rat
From the Super Mario Wiki
Paper Scaredy Rats are paper forms of Scaredy Rats that appear as enemies in Mario & Luigi: Paper Jam. In battle, they attack by walking single-file into one of the Mario Bros. Jumping on one Paper Scaredy Rat results in the rest of the group running away in pursuit of a larger group. They can also attack by running in circles around one of the bros., which must be countered with a hammer to prevent them from running into the bro. Paper Scaredy Rats are found in the Twinsy Tropics Dungeon.
Rare, shiny variants can also appear in place of the regular Paper Scaredy Rats in the same area. These Paper Scaredy Rats have greater stats and always drop either an Refreshing Herb or a Double 1-Up Mushroom when defeated, though their methods of attack remain the same.
