Magon
Magons are weird monsters in Wario World. They are very weak with a weak chomp attack, and a single punch will outright defeat them. They are first seen in Greenhorn Forest. Wario had to beat a lot of these. The first Magons seen in Greenhorn Forest and Greenhorn Ruins would not hurt Wario, but later they would.
Every Magon or Magon-like enemy encountered also has a larger version. The Magons, Skeletal Magons and Snowmen try to hit Wario with a mere swipe. The Clowns, Wolves, Puppet Magons and Mummy Magons swipe too, but they also have a much more powerful tail spin that knocks Wario out for a few seconds. They must be stunned with a punch or three punches first, then Wario had to execute a Piledriver, Wild Swing-Ding or Power Throw to defeat them.
Other varieties of Magons would appear is later levels, including Skeletal Magons, Clowns, Snowmen, Wolves, Puppet Magons, and Mummy Magons.
