Kamilo beach lost & found

Google sleuths and polyglots! I need your help solving a collection of (s)pacific mysteries. Instincts honed in the 80s served me well in identifying the green lump of plastic above as a battlecat saddle from He-Man (Panthor’s actually based on the colour), but do you have any ideas about the rest of these objects found washed up on Kamilo beach in Hawaii?

Much of the plastic circulating the Pacific remains anonymous, even after it gets caught in nets or picked up off beaches. Broken into pieces, labels and contents long gone, there are few if any clues to help trace waste to its possible place of production, consumption or disposal.  Identifying objects and bits of writing is not only incredibly satisfying (especially compared to counting bits of confetti), this information helps researchers track where waste comes from and how it circulates in the ocean.

Some kind of game pieces? Glassware but what does it say?

These are Japanese survey stakes, but from where/when?

Found in a beachcombers closet, not on the beach:

The owner loves the shirt but would like to make sure it’s not advertising something offensive before she wears it.

Finally, Noni’s toy collection, in case you’re still in mystery/nostalgia mode.

Comments appreciated!
