Evolution, survival of the fittest and all. If some idiot manages to do self harm with a playmo flag pole/spear/finial... I say... LET THEM. 
But…..are you willing to say the same thing for cats and dogs ? F-em ….survival of the fittest. If some company wants to make a potentially dangerous animal toy….it’s the idiot animal who self harmed themselves.
I’m not wanting playmobil to be all made out of rubber , but there needs to be a balance, otherwise we’re all playing with lawn darts and beyond
