Mommo slimes are weak but annoying monsters that will vomit slime around themselves constantly. The slime can deal slight acidic damage to you or your equipment but can also glue you to the floor, possibly preventing you from walking until you escape.
There are two varieties of mommo slime: flat and conical. Conical slimes are made of [[yellow slime]], which is very acidic (1/4th the acidity of [[sulphuric acid]]), whereas flat mommo slimes are made of [[brown slime]] which is less acidic (1/8th 16th the acidity of [[sulphuric acid]]), but far stickier.
It is strongly advised that you take on mommo slimes from afar with whatever means you have available, lest you become stuck in place while your equipment melts off your body.
