Lolly Gobble Choc Bomb was an ice lolly - strawberry ice cream, dipped in chocolate, covered in Hundreds & Thousands, with chocolate at the centre.
I think I only ever had one, for some reason my mum always discouraged me from buying them. But what a wonderful name!
I found details about it on the Lyons Maid website, which has a list of the various products it has sold. Lolly-nostalgia heaven!
