A dakimakura, AKA a body pillow. Needs an anime character on it, obviously.
Of coure the large breasted, scarcely dressed waifu of questionable age shall still be referred to as “Wilson”
A 1ft tungston cube
How about a pet rock?
The severed head of a man named Wilson.
Oooh, the dead body of Owen Wilson.
Or the frustratingly unkillable body of Wade Wilson (Deadpool)
HEADPOOL!
Magic 8-Ball
This time Wilson can kinda sorta actually talk back.
The corpse of Harry Potter that’s slowly coming back to life
Oh wait, that movie exists already
Couch
Starring JD Vance
couch cushion
This is inexplicably the best answer yet. Everyone else is working so hard to think outside the box that the box is inside-out.
Plus, now you can include a love scene.
I have absolutely zero interest in making this movie political.
Then I’d go with airplane seat cushion instead.
The couch cushion works fine. Couch cushions appear in real-life situations all the time and simply having one in the movie cannot be construed as making a statement on the kind of conduct that we as a nation are willing to accept from our vice-presidential candidates.
A bowling ball. Can change some of the script so he catches it before it rolls off the raft but he falls in the water with it. He’s too heavy and weak to make it back to the raft so he has to let go and watch it immediately sink or he’s taken under too (also a good reference how it’s hard to save someone from drowning when you’re near drowning yourself). Definitely thought of a dildo first till I saw everyone else put it up though.
Some bowling balls float.
Can I just suggest that to mix things up a bit, this one should be set on a peninsula.
Ooh, I’ve thought of one: a helium balloon. Imagine the tension as he occasionally forgets to hold the string!
The same volleyball, but he’s imagining it and he’s the only one who can see it.
Plank
An MRE. When supplies dwindle, our protagonist is faced with a tragic choice.
Oh wow look at what the tides have swept ashore. A Pringles can, some rubber gloves and a few sponges.
