Destroyable walls are interactive objects in Slime Laboratory.
Destroyable walls are made up of several metal squares. Those squares range in sizes and come in the colours pink, grey, silver.
Once the slime has got one bit of slime or more, he can destroy certain walls. Often behind walls is floppy disks but mostly other passages. Destroyable walls will sometimes delay the player as when it is pushed over they will sometimes land in front and not move but then they will quickly disappear.
