In both Papa's Cupcakeria and Papa's Pastaria, there is a badge called Scarlett and the Shakers which one must earn by serving Marty, Clover and Scarlett. After Rudy had made his debut, this badge could be earned in Papa's Pizzeria To Go! by serving all four members of the band. In Papa's Bakeria, there is a sticker of the same name that is earned after serving all four of them.
- If a player decides to use one or two custom workers when playing Papa's Cheeseria, the workers accompany the band during the concert. One worker will play the saxophone while the other (if a second custom worker is selected) shakes the maracas.
- Their outfits incorporate the four suits from playing cards; Scarlett (hearts ♥), Rudy (spades ♠), Marty (diamonds ♦) and Clover (clubs ♣).
- All of the members of Scarlett and the Shakers have become workers, with Marty being the first in Papa's Burgeria and Clover being the last in Papa's Sushiria.
- Janana acts as their agent. 
- All of the members work in gamerias that serve savory food.
