You walk home after a long day in the mines, you go to stash your spoils of labour when you think you hear a quiet snickering from a distance. after stopping to listen, you hear no more noise, so you shrug it off and go to open your chest when...
BOO! A GIANT Jack-In-The-Box jumps out at you!
Now imagine that, but your the one snickering, and your friend is the poor soul opening his chests. This is the Jack-In-The-Box mod made for Modfest: Toybox! It looks like a regular old chest until you go to open it, which is when the towering jester springs to life!
Sounds fun, right?
