um well no he couldn't have got them from a hunting trip to humans
.THose were small skulls- any Yautja who kills a human child except for Disgraced ones will be followed with disgrace and dishonor
.Those couldn't be fro mthe Weyland gaurds, they were all hung and far from dangerous to the Yautja- even as teens
.Even the one at the bottom, that weyland gaurd's head was sliced and skull un rip-able
. and um for some other reason.. i dunno but you get the picture
maybe Monkey's on their home planet for practice- humans are evolved monkeys after all
