Prep the glass: Rim a glass with sugar by dipping it in water or lemon juice, then sugar. Hang a couple of gummy worms on the rim and drop one or two inside.

Shake the cocktail base: Fill a shaker with ice, then add vodka, raspberry liqueur, lemonade, and pineapple juice. Shake for 10–15 seconds until well chilled.

Pour and add fizz: Strain into the prepared glass filled with fresh ice. Top with a splash of club soda or lemon-lime soda.

Garnish and serve: Add a few more gummy worms for fun. Serve immediately with a straw.
