Blue Slime

Blue Slimes are the second level of slimes, being just a bit stronger than a Green Slime. It drops up to 2 Gel and some copper coins when killed. In the 1.2 update for the PC it also has a small chance of dropping a Mechanical Worm or a Mechanical Skull, provided that hardmode has been entered, and those bosses have not yet been defeated. They can jump through a 2 block space. Blue slimes are immune to the Poisoned debuff and follow the Slime AI.
