She-Ra: Princess of Power (1985)

S1E48 Birds of a Feather

Red Eye, Kowl’s cousin, arrives with dreams of joining the Horde. Eager to prove his worth, he offers Shadow Weaver a pair of Kowl’s feathers, which she uses to craft a magical spy to infiltrate the Whispering Woods. The plan works, and the Horde gains a dangerous new vantage point—but the cost of Red Eye’s ambition may be more than anyone expects.
