Brenda Song is joining BFF Ashley Tisdale on her animated Disney Channel series, Phineas and Ferb.

The 20-year-old Suite Life actress will voice Wendy, a girl who competes with Candace (voiced by Tisdale) for a job at the hot dog stand where Jeremy (voiced by Mitchel Musso) works at.

In the upcoming episodes, “Unfair Science Fair” and “Unfair Science Fair Redux,” Baljeet is building a portal to Mars for his school science fair but he just can’t seem to make it work. Phineas and Ferb step in to help him finish it off. Candace feels rejected by her friends and decides to step into the portal of Baljeet’s finished science fair project. She is transported to Mars, where the Martians all worship her.

Both episodes air THIS Friday, March 20 @ 830PM ET/PT on Disney XD.
