In Friends, what is the name of the holiday armadillo costume character?

The holiday armadillo costume character in Friends is called the Holiday Armadillo.

Ross creates the character in “The One with the Holiday Armadillo,” a season-seven episode. He wants to teach his son Ben about Hanukkah, but he cannot find a Santa costume to rent, so he chooses an armadillo costume instead.

Ross presents himself as Santa's half-Jewish friend, the Holiday Armadillo. When Chandler arrives dressed as Santa, the scene becomes a comic contest over who gets to explain the holiday to Ben.

The character is often mistakenly called a Hanukkah armadillo, but the show's credited and commonly used name is Holiday Armadillo. The costume is tied specifically to Ross's attempt to combine Hanukkah education with the Christmas imagery Ben already knows.
