Dolly
Don’t let the big eyes and tiny paws fool you—Dolly is more than just a pretty face. Though she may give off strong “I’m just a baby” vibes with her soft glances and petite frame, she’s got a spunky spirit that makes it clear who’s really in charge. One look at her is all it takes to motivate her mom, Lily, to work a little harder—after all, someone has to fund Dolly’s pepperoni stick obsession.
