This is Box Monster just before it rose again.


However - Mister Bones was keeping watch, and set about conquering it!


More conquering!


Permanently vanquished!


Still vanquished!


As if it weren't enough that Box Monster could rise again at will until permanently vanquished, Box Monster seems to have evolved enough to procreate. This smaller blue box is apparently the Spawn Of Box Monster!


Mister Bones can multitask! Here, he holds down the carcass of Box Monster while combating the Spawn Of Box Monster.
