Slimes are the most common type of monster the player will fight, with a surprisingly high spawn rate during the day. They come in multiple sizes and colors, each of which has different health and damage. Slimes float in water.
All slimes follow basic Slime AI and attack by hopping onto the player. All types drop 1-2 Gel except for Corrupt Slime, which drops 2-4 gel. This is a vital ingredient in crafting Torches, Lesser Healing Potions and Sticky Bombs. In addition, it is the ammunition used when firing a Flamethrower.
Slimes spawned on or near the surface are usually neutral and do not chase the player unless provoked or if still on-screen after nightfall. Slimes spawned underground are always hostile, however. Green, Blue, Red, Purple and Yellow Slimes usually spawn on or near the surface. Mother Slime, Baby Slime, and Black Slime can only be found underground. Pinky may appear anywhere, although rarely.
Lava Slimes will only spawn in the Underworld and do not receive damage from lava. It has an orange glow similar to that of the molten armor.
Corrupt Slimes and Slimers appear in The Corruption and Underground Corruption. Illuminant Slimes appear in The Hallow and Underground Hallow, whereas Toxic Sludge is found anywhere in the Underground. All of these are found only during hardmode. Also found during hardmode is the Gastropod which drops 5-10 gel on death.
