What is this bit of plastic?

[Trunks]

I've been tidying the truck out & found a random bit of plastic!

Is it something important (nothing's stopped working ), or has the previous owner left their lunch box lid





Cheers

Don't throw it out till the grown ups answer but I don't think that is part of a surf.

Doesn't seem to fit anywhere. Only thing I can think of is it's off the bottom of the seats.
