Time to answer few of these ridiculousness.
Yes, I had a dyslexic, brain fart moment and reversed giant and miniature while typing. Doesn't change anything though.
Size density and mass are not necessarily corelated - especially where magic comes into play
Boo's is able to magically change his mass and density - he can make himself REALLY heavy.
If Boo can change mass and density this will beg a question why would it try to kill it's party members by changing mass to something heavy instead feather?
Are you suggesting Boo is evil? That would be blasphemy beyond recognition and earn spot in ignore list (if this forum has one)
Well a miniature giant space hamster might still have the same weight as a giant space hamster, just a lot more density
...maybe THAT is what caused Minsc's condition
No it can't. Boo is seen climbing on creatures shoulders and arms without them getting crushed.
Boo can also explode enemies from the inside (cit) :P
No it can't.
As you see I take Boo dead serious!
