Slimes are enemies in Solomon's Key. They are blobs that appear in three colors and varieties. They appear from generators and also do not appear in the NES version of the game.
Green[ | ]
Green Slimes are the slowest of all the slimes. They bounce along the floor from block to block. They can also slip between blocks and through walls. Their unpredictable nature makes them extremely dangerous to deal with.
Orange[ | ]
Orange Slimes are a little faster than Green Slimes. They occur on much fewer stages than Green Slimes. You can never tell where they are going to go next, so your best bet is to avoid getting close to them as much as possible.
Purple[ | ]
Purple Slimes are the fastest out of all the slimes. They will only appear on one stage in the entire game, and only if you happen to destroy one of the existing enemies with a fireball. So chances are likely that you will never actually witness the speedy Purple Slime at all.
