The Berenstain Bears - Season 2 Episode 3 Too Small for the Team

Sister wants to join the girl's soccer team, but Coach Brown thinks she's still too young to take part because the cubs are bigger than her. Sister grudgingly accepts the position of team manager instead. It's a tough job, and Sister's perseverance doesn't go unnoticed by the coach, who ultimately invites her to play in a big soccer match when a team member goes home sick.
