Chocolate sprinkles!

No

It is that flat metal bar with a hook at the end for opening car door locks.

Yes; they are those short pry-bars that burglars use to open doors and windows.

I have no idea

This looks like something you find in your intestines? worms

Oh, now I know I love jimmies.

I thought I did. Hopefully, it won't make you laugh too much when I say that we used to get them on our ice cream cones.
