Hubble is a baby bird. He appeared in The Nest Hats Craze!
When Blythe was watching a fashion show, the Biskits pushed her, causing her to bump on a tree, which dropped a nest on her head. Blythe kept the nest on her head as she went back to the Littlest Pet Shop, where she found out it had an egg inside. Concerned about the egg, Blythe left to search its mother, leaving it under the pets' care.
After some discussion over who would keep the egg warm, Russell laid over it, helping a bird to hatch shortly after. Russell named him Hubble, and he promptly called Russell "mommy".
Russell tried to teach Hubble how to fly and to feed him, with disappointing results.
Blythe later returned him and the nest to the tree, where his mother could find them.
