Littlest Pet Shop - Season 2 Episode 9 A Day at the Museum

After losing a ball while playing catching, Minka and Penny Ling try to retrieve it when it rolls into a natural history museum. Blythe tries to retrieve the two without losing all the other pets, but finds out that the museum disallows animals. She conceals the rest in her bags and backpack, but as she spots the two that were missing, Zoe flees from her bag upon inspection from the museum's security guard. Now with three of the pets missing, Blythe must manage to find them all, eventually losing the rest in the process: Sunil and Vinnie in the taxidermy section, and Russell in a supply closet.
