Melody Pops (Chupa Chups, 1990s)
This British candy actually plays real music. What?! Melody Pops are strawberry flavored lollipops shaped into a whistle. Yes, you could hear a whistling sound from them. The stick acts as a slide. Though Melody Pops may not be readily available in candy aisles anymore, I have found Melody Pops for sale via Amazon, eBay and Candy FunHouse. You do have to buy in bulk.
