No, I think Peter just hasn't run across any of his old childhood mementos--particularly his "woogy."
This is my theory--most woogies end up in such a decrepit state that there is nothing left to save. Mom open's the dryer one day only to find a pile of yarn.
The loss of one's woogie was deftly handled by "Mr. Mom."
