Wow, I'm going to use variables (h>heads, e>eyes, a>arms):
a. 2h, 2e, 4a __ 73=a+b+c+d, 27=g+h+e+f
b. 2h, 2e, 2a __ 28=c+d+g+h, 72=a+b+e+f
c. 2h, 3e, 4a __ 21=a+c+e+g, 79=b+d+f+h
d. 2h, 3e, 2a __ 12=c+d, 88=a+b+e+f+g+h
e. 1h, 2e, 4a __ 9=g+c, 81=a+b+d+e+f+h
f. 1h, 2e, 2a __ 8=a+c, 82=b+d+e+f+g+h
g. 1h, 3e, 4a __ 3=c
h. 1h, 3e, 2a __ You are looking for f (normality, or, if you like, any case that does not present the unusual features mentioned)
c=3
g=9-c=6
a=8-c=5
d=12-c=9
e=21-a-c-g=21-5-3-6=7
b=73-a-c-d=73-5-3-9=56
f=72-a-b-e=72-5-56-7=4
Please check if I am wrong.

101-you forgot to mention the invisible alien that is a hyper-intelligent shade of the color blue.
