Jelly

Jellies are entities that use some kind of medium to take shape. They appear in Castlevania 64 and Castlevania: Legacy of Darkness. Jellies of mud are called Dirt Men, those of ice or crystals are Ice Monsters, and those of blood are Blood Monsters. These creatures can collapse into puddles of material on the ground and avoid being attacked. They can then rise from the ground forming a humanoid shape and spew materials at their opponents, which may Poison them. A creature called a Tanjelly in later games acts similarly to s Slime.
