Fievel's American Tails (1992)

S1E6 The Legend of Mouse Hollow

Chule has created an innovative 'mouse packing machine.' Meanwhile, the school stage production starring Tanya attracts a crowd of mice. Fievel is initially disheartened by his assigned role, but his part becomes unexpectedly significant when Cat R. Waul kidnaps the teacher, putting the play on hold. Instead of the anticipated performance, he orchestrates a singing concert, shifting the focus of the event entirely.
