In his fight, Djimmi turns into several Columns and Cuphead (or the other one) should destroy them. Since the size of Cuphead vary from the size, I'm going to use 1 m, most of the time he is less than the half of the height of a "normal" person.
- Cuphead = 89 px = 1 m
- Column diameter = 222 px ~ 2.5 m
- Column height = 142 px ~ 1.6 m
- Volume = pi*1.6*(2.5/2)^2*1000000 ~ 7854000 cc
- V. Frag. (Concrete) = 20*7854000 = 157080000 J = 37.543 tnt kg (Room level)
It takes a couple of bullets to destroy it, but I think that one mortar can one shot it iirc.
