Additional models and textures can be found on the addon page "LittleMaidMob Enhanced [Textures addon]"

This fork was made by Legojr, the original page for the mod can be found here.

This mod, although abandoned, works as of the latest forge version, and I haven't found incompatibilities still (there could be some problems with Aether II but I haven't done any tests).
LittleMaidMob Enhanced is another version of the LittleMaidMob that is taking a bit of a different direction than the other developers of the mod. This version aims to increase compatability, stability and add a bunch of features that allow your maid to do more and let you control more of what they do.

Extensives guides for the mod can be found in the fork's and the original mod's forum posts.

In short:

find, or craft a spawn for, the maids.
give them a cake.
give them a tool.
activate them with sugar.
enjoy.
