Paper Chain Chomp
From the Super Mario Wiki, the Mario encyclopedia
Paper Chain Chomps are paper forms of Chain Chomps that appear as enemies in Mario & Luigi: Paper Jam, encountered in Neo Bowser Castle along with the Paper Shy Guys that wield them. If the Paper Chain Chomp is defeated, the Shy Guy will flee, resulting in no EXP from it. Paper Chain Chomps attack like their regular counterpart, by lunging at the player characters. They are the only basic paper enemies without a shiny variant.
