According to Entertainment Weekly (EW), Goodwin found out through an email from her publicist that "Sesame Street" wanted to get her on its show. She was very excited upon learning about it because she grew up watching the children's show with her sister.

"I believe my response was in all-caps, and there was a lot of cursing and happiness," said Goodwin in the Entertainment Weekly report.

Abby Cadabby, the cute muppet that Goodwin is partnered with, is handled by puppeteer Leslie Carrara-Rudolph. Abby and Goodwin reportedly hit it off immediately upon meeting each other on the "Sesame Street" set.

The pairing between the fairy muppet and the girl who plays Snow White, who is a princess, is perfect for the "Sesame Street" episode titled "The Princess Story."

Goodwin got rave reviews from "Sesame Street" director and head writer Joey Mazzarino who said that the OUAT star is like a muppet herself.

"What a light. She is like a Muppet herself. When she and Abby started to play, it really felt like a little kid playing with another little kid. Anytime you get a grown-up who still has that little kid side of them and they go to that place - it just makes me so happy," said Mazzarino in the EW report.

Goodwin, who is currently engaged to co-star Josh Dallas, who plays Prince Charming in OUAT, is also pregnant with their first child. She is excited to show her future kid the "Sesame Street" episode that she filmed.
