Slime Monsters are a set of monsters, identified as slightly transparent blobs that slowly hop toward the player in an attempt to attack. They are most likely going to be the first enemies you find in the game. They are the most common enemies in Terraria, able to spawn at any time of day and in nearly every biome. There are many types, all differing in appearance, stats, and behavior: As a general rule, however, the stronger the slime, the higher and more frequently they will jump at the player. They will all drop gel and coins.
