Dory does go through her own character arc in Finding Nemo. She suffers from short term memory loss, which affects her friendship with Marlin throughout their adventure because she initially just comes off as annoying. As the film goes on, she reveals to be intelligent in her own way (speaking whale, knowing how to read). In the end, her recent memory is restored and is ultimately what reunites Marlin and Nemo.

Yesss and Shank show up and help Ralph and Vanellope. Nothing about their characters grow or develop by the end of the movie.
