Flipstring

From the Super Mario Wiki

Flipstrings are scorpion-like enemies from Wario Land: Shake It! Because of their stingy tail, Wario can't jump on them. With an Earthshake Punch, Wario can put these enemies into their shells, so Wario can throw them. Due to their shells, Flipstrings resemble Buzzy Beetles, although they aren't related to each other.
