About this Mod
🐷 Useful Pigs

Throwing a glow berry at a bat will give one nearby mob glowing, helping to find new caves!
Also features an advancement for doing so.
🐻 Useful Polar Bear
Throwing raw salmon at a polar bear will give all nearby players strength!
Also features an advancement for doing so.
🦑 Useful Squids
Glow ink sacs can now be used to craft spectral arrows.
When damaged, squid ink now afflicts players in range with brief blindness. [3.0+]
More helpfully, glow squid ink gives players brief night vision and glowing! [3.0+]
⚙️ Configuration
Use /function usefulmobs:config to enable and disable all* features! [3.0+]
*The spectral arrow crafting recipe cannot be disabled with commands, and must use a separate datapack instead, sorry =(
Note
All mobs that consume items (Bats, Polar Bears, and mounted Pigs) will only consume one at a time, so it is safe to throw a whole stack!
