Bandit brings Bingo and Bluey to the supermarket to get some shopping done. But in the car ride there the two kids have a debate about who is the favorite child—note it’s always the oldest. When Bandit tells them that parents can’t have a favorite, Bluey goes full takeover and plays a game where she is the mom and Bingo and her dad are her two kids. Bingo is clearly her favorite and she ends up saying that out loud and really hurting Bandit’s feelings (in the game). So Bluey learns a lesson about favoritism and treating people equally.
