CREDIT GOES TO YOUSEF ON DISCORD FOR THIS CALC. IT WOULD HAVE NEVER BEEN POSSIBLE WITHOUT HIM.
So.. this is the feat
got nothing to do other than that I'm gonna use a method similar to cutting feats ways, you will see
The first end:
Undyne is 2.4 meters
I'm gonna use 2.1 because we don't see all her body
210 cm = 276 px
height of the core is 1073
1073×276÷210=1410.228571429cm
diameter of the bone is:
36 px
36×276÷210=47.314285714cm
raduis=47.314285714÷2=23.657142857
so since we have everything
23.657142857×23.657142857×1410×π=789121.175500674π
=
2479097.28775 cm³
I'm gonna assume 85% hollowness for obvious reasons
0.15×2479097.28775=
371864.5931625
Also, since it wasn't really a clean piercing I'm gonna use Violent fragmentation
also, using titanium's values because that material was resisting lava's temperature
371864.5931625×760=
282617090.8035 joules
which is small building
another end is by using an assumption of 12 meters right away(as dimensions are not really consistent in horrortale due to bad art)
though, it would still be small building
