They're playing with everyone - S1.E30

Tau has a favorite bench in the park where he reads his books. Right next to it, Nick & Terry discover a hole where ants were getting into. They decide to make their own silly rule and not let anyone near the ant hole. Buddy tries to convince them that it is not fair, but can't succeed. However, as soon as Tau teaches them a thing or two about ants, they all become good friends.
