.mkslime
From WikiManual
.mkslime ----- I can make a layer of slime on my body to protect me from your ties. Trouble is it slowly dissolves away. Storing a positive value in .mkslime will cause that amount of slime to be made (to a maximum of 100 per turn) and a negative value will cause slime to be removed. You lose 0.1 energy for 1 point added or removed.
