Is there any significance to the "big name toys" in Fallout 4?

Scattered in among the random junk in Fallout 4 are a couple of recurring toys, that are of rather large size. You find parts for a Giddyup Buttercup (and a complete one, at one point), a lot of Jangles the Moon Monkey, and even some alien toy.

Is there any significance to collecting these beyond just their value as junk parts? Should I bother to pick them up or keep any around outside of my workshops?

I checked the wiki and most junk items have no "real use" besides being scrapped for crafting or use for decoration. If you want to check on any items and their use (especially the junk) just got to the wiki I used.
