Sour Blue Raspberry Bubble Gum.
Bubblegum from FLV is stellar.
Blue Raspberry LB + Blueberry HS is a great combo for a solid blue raspberry candy.
Cactus for some juiciness.
Lemon Mix to make the berries pop, and add some more sour and tartness.
Sour Apple from FLV brings some tartness.
Candy Wizard from FA is a nice texturizer, brings some sweetness, and drives home the candy profile.
