Plot
The episode begins when Alberto and Amigo go to Arthur's house and Alberto gave Amigo's supplies to Arthur. Before Alberto was leaving he showed Arthur a trick. Amigo didn't catch the ball and then Alberto left, waving goodbye. Arthur daydreamed that Alberto came back home and was amazed to see Amigo flying high with a tennis ball. After Arthur's daydream he saw Amigo missing. Meanwhile, Pal was giving Amigo a welcoming tour of the house. After the tour Arthur was playing with Amigo Pal felt left out. Then Pal went inside and upstairs to D.W's room. Kate was there playing with building locks. Pal went back outside and throwing his ball against the chimney and saying Nice Catch and Good Boy over and over again. Then Nemo watched from a tree branch and scoffed at Pal.
