Swooper is a bat creature that hides in dark places, hanging from the ceiling. They attack by swooping down and suck HP from Mario and his partner (although in the original Paper Mario, they only swoop down and hit him). The only way to get a Swooper from the ceiling is to use a quake attack, use a partner that can fight enemies at high altitude (like Parakarry or Madame Flurrie), or use the throwing hammer badge. Sir Swoop is this type of enemy, although he doesn't appear in enemy battles. In Super Paper Mario they're only found in Gloam Valley and Merlee's basement.
