The three children travel up the mountain, but Klara stops halfway so that Heidi can run on ahead without pushing her wheelchair. Heidi runs ahead and is joyfully reunited with her grandfather. Back halfway down the mountain, Klara's kitten Snowball is attacked by a hawk. Klara crawls out of her wheelchair and uses a stick to fight off the hawk. Klara then discovers that she is able to stand. Klara's father arrives and together they celebrate Klara's mobility and Heidi's return.
