Slime

Slime tends to bounce or crawl around and often is able to defy gravity.

Vampire Killer
Slime is one of the only enemies that appears in Vampire Killer that does not appear in the original Castlevania I. It is "dropped" when striking a booby trapped candle, and proceeds to move along the ground trying to attack Simon Belmont

Castlevania: Symphony of the Night
Small slime and Large Slime appear in the Catacombs stage in the regular castle. The small slime is rather slow and moves toward the player, and is colored green, it can crawl along floors, walls, & ceilings. The large slime is brownish/red in color and is significantly bigger than the small slime, it seems to have "teeth" of some sort which it does not use for attacking, it also possesses a leaping attack in which it will jump forward a short distance for contact damage. Immune/Tolerance: cut, Weakness: club.



Castlevania: Legacy of Darkness
In the battle with the first boss (Sea Serpent), this boss spits green Slime. But this Slime not harm you, you just stop over for the Sea Serpent hit you.

Castlevania: Harmony of Dissonance
There are more than one type of slime (despite one entry in bestiary):

Orange and Purple - petrifies

Yellow - curses

Green - poisones.

Also, killing them produces 2 Tiny Slimes which have normal damage. There is also a boss version of slime.

Aria of Sorrow
The Slime in the Aria of Sorrow series can be found in the Underground Reservoir and the Chaotic Realm.It can poison Soma upon contact and can be colored blue or purple,although this does not affect damage whatsoever.

Castlevania: Portrait of Ruin
In Castlevania: Portrait of Ruin, the slimes look and move just like their counterparts in Castlevania: Dawn of Sorrow. They slither, not hop, along surfaces, never leaving a platform unless a hero passes by over, under, or to the side of them. Then they will leap up, down, or to the sides in order to hit the hero.

While they don't cause any status effects (also true for Dawn of Sorrow), they do have a nasty new feature. When a hero walks up to them, the Slime will stretch itself outwards, and try and hit the hero via a "Whiplash" effect. This makes them, and their cousin the Tanjelly more dangerous than before!
