Mother Slime

The largest of ordinary slimes, the Mother Slime starts spawning when you reach the Cavern layer. It takes up 2x3 blocks of space (as opposed to the player: 3x2).

Similarly to Baby and Black Slimes, the Mother Slime blends slightly with the background of the Cavern layer, making it difficult to detect. As such, it can often catch players off-guard.

Like all other slimes, they drop coins and sometimes Gel when killed. In addition, they spawn 2-3 Baby Slimes upon death.

Mother Slimes are immune to the Poisoned debuff.
