That's So Raven (2003)

S2E2 Don't Have A Cow

Alana is gearing up for her Halloween bash, and Eddie is already on the guest list. Meanwhile, Raven is upset since Alana didn’t extend invitations to Chelse or Rae. The two left out girls find themselves at the Chill Grill, where Alana's party is set to take place. Victor serves them burgers, and unsuspecting Chelsea, a vegetarian, bites into Rae's meat burger. Rae devises a plan to use Viv’s spell book to compel Alana to invite them. The spell works, but Chelsea accidentally drops her No-Cow pin into the potion, causing them to sprout cow ears. In a panic, they search for the book Eddie used for his costume. How will they retrieve the book and blend in at the party as cows? Meanwhile, Cory and his friend William are out trick-or-treating, leaving Victor behind.
