This data + resource pack requires the mods Environmental and Create- hopefully that's obvious.

Slabfish are adorable creatures probably sent straight from the heavens down to the overworld. They can hold your items in a backpack, follow you around, wear sweaters, and be altogether amazing.
But as a master Create engineer, creating all sorts of moving marvels and spinning machines, wouldn't it be great if your little slabfish friends could look the part too?
This data and resource pack allows you to put engineer's goggles in the sweater slots of slabfish, giving them their own pair of kinetic readers; or giving them an electron tube to look like a cyborg slab. Additionally, it lets you put andesite, copper, or brass casings in the backpack dye slot, so they can sport snazzy new casing packs.
Enjoy!

If you include this in a modpack or something similar, please credit and link this page, thanks!
