yeah they do
They stay relatively the same in terms of hight.
goos point, BUT. the still grow wide which is thw main factor here
stunts eye stay the same size but head changes size
the elastick part that gose around the back of his head just strestch thats how small swimming gogles fit on a big head
it is called slugcessories and it grows when the slug transforms like king of sling's
phosphoro glasses and like the sheild on stuntz in his slugisode
Cool!
