Episodes suggesting a conflict

  • In Take the Plunge Part 1, when Rocky spoke to Tennis Ball, he seemed a bit annoyed.
  • In Are You Smarter Than a Snowball?, after Tennis Ball said Rocky should learn how to write with his legs, Rocky kicked him, and seemed happy as Tennis Ball rolls away.
  • In A Leg Up in the Race, Tennis Ball seemed happy when Rocky lost 15 points.
