Slimer

Introduced in the 1.1 update, Slimer is a flying member of the Slime family that only appears after Hardmode has been enabled. It only spawns in areas overtaken by the Corruption, but can be found both underground and above ground.

Slimer appears to be a purple orb with wings, and will hover sluggishly around the player's head in a fashion similar to that of a Vulture. It is relatively weak, having only 60 Health in its flight form. It will drop its wings when 'killed' initially, becoming an ordinary slime in terms of habits, but will still be called a Slimer.

Once a Slimer is wingless, it will start out with a new health pool of 90, and behave like any other slime, including the usual drops of gel and coins.

Slimers seem to use the same wing model as the Demon Wings. Despite this, the monster does not drop them.

When the Slimer has it's wings, the slime is in a perfect circle even though it doesn't have any sort of casing.

Trivia

 * The name Slimer was given to the flying globular green ghost in the Ghostbuster movies, and the various subsequent cartoon series. The name may be a reference to this ghost, as in the movies the character Peter Venkman (played by Bill Murray) states after being ran over by Slimer “He slimed me!” and is covered in a slimy gel much like the gel that slimes in the game drop. Since the ghost is mostly an annoyance in the movies, much as slimes are in the game, it indicates another potential nod to the franchise.
 * In short both are annoying and can fly.
