Bio and Personality
After a fun day, Stacy and Becky start badgering Marlene to do wild and crazy things with them. Eventually, Marlene gets so annoyed she tells them to stop badgering her. Unfortunately, badgers do not take kindly to badger stereotyping, so Becky and Stacy start chasing her around, telling her that when they're finished, her own mother wouldn't recognize her (although, as Kowalski points out, her right foot is very distinctive; even her mother would recognize that).
Stacy and Becky are later defeated when they and Marlene fall into the park, causing Marlene to turn into her feral self. Stacy is notably used as a boomerang by Feral Marlene to knock out Becky. After that incident, Becky and Stacy appear to respect and fear Marlene, since they all have a picnic with the penguins in the park.
Stacy and Becky both make a reappearance in Tunnel of Love, where they fall in love with the beavers and romance interferes with the beavers' work.
