Found in my own garage

Before Gulp! came out I used Salty Dogs, Bass Assassins, Jelly worms, etc. for weaks and I actually bought bait ( !! ) like spearing and squid for fluke. Somewhere along the line, before Gulp!, I bought these pictured. Can I assume they are scented as the Berkley Power Worms I used for freshwater bass are/were? Although soaking plastics other than Gulp! in Gulp! juice never seems to work as well as real Gulp! I wondered if the dozens of these wrapped like this and tucked away in an old set of drawers (actually my childhood dresser) could be added to Gulp! juice with any degree of effectiveness.
