Fawflant

Fawflants are Fawful-like, drill ant enemies found in Mario & Luigi: Bowser's Inside Story. They live underneath Toad Town. In battle, they have two attacks. One (only if two or more Fawflants are in battle) is attacking either Mario or Luigi at the same time, or attacking them both at the same time. This can be countered by jumping. The other attack is simply walking backwards into one of the brothers, so the brother will take damage and possibly be poisoned if they are hit by the drill. This move can be countered by using the hammer.

In the overworld, they will start a battle by doing something similar to one of the attacks; walking backwards with the drill in action.

Also, in Toad Town Caves, Mario and Luigi will meet two Fawflants disguised as Toads, who acts as guards for Fawful while he's stealing the Dark Star. It also shows that Fawflants are capable of speech and shapeshifting.
