Cindy Lou Who is a lot of trouble.

The wee tot who was not more than 2 in Dr. Seuss’ “How the Grinch Stole Christmas” is now an alcohol-swilling, foul-mouthed Whoville outcast in Matthew Lombardo’s comedy “Who’s Holiday.”

If Brandy Johanntges, who plays Cindy Lou, gets into any trouble, there’s no one to bail her out. “Who’s Holiday” is a one-character show, so all the dialogue — written in Seussian rhythms of Theodore Geisel’s children’s books — and all the action come from Johanntges.

She also starred in Millennial Theatre Company’s inaugural production of “Who’s Holiday” in 2024, and she will do four shows over two weekends starting Friday at Hopewell Theatre. This isn’t Johanntges’ first stint in a one-woman show. She played 40 different characters in Selah Dessert Theatre’s production of the comedy “Fully Committed” in 2023.

“That was way scarier than this,” Johanntges said. “But this one is scary. Being up there alone is scary, but when you do a lot of theater, you have to give it a try, just to see what it’s like.”

Solo shows come with advantages and disadvantages.

“Well, the positive part about it is, if you mess up, nobody knows. If something happens and you’re not sure where you are or whatever, you can play it off and get back to where you’re supposed to go and no one will know,” she said. “But the bad part is, no one is up there to save you. You’re by yourself. And if you do screw up, you don’t know where to go. If you’re playing off another person, at least if they say something, it’ll trigger you. But, no, you are just you are up there by yourself. So yeah, it’s definitely difficult … (But) once you actually do it and accomplish it, you feel like, ‘My God, there’s nothing I can’t do.'”

The play opens with Cindy Lou Who, recently released from jail, decorating her trailer for a Christmas party. But it soon becomes evident that none of the invited guests plan to attend.

“When I first read it, I was like, ‘Oh, my God, what have they done to this poor character? But it’s so funny, and it is very heartwarming,” Johanntges said. “She never loses hope. She’s always very happy. It’s amazing what they’ve done with this character. I don’t know the person who wrote this. I don’t know what he was thinking, but he must have a helluva of a sense of humor.”

Joe Asente reprises his role as director. Johanntges said they’ve made a few tweaks here and there, making some changes to the set decorations and some of the sight gags in the play, but based on audience reaction last year, it didn’t require many changes.

“We’re a little more relaxed, because we had absolutely no idea what was going to happen last year, and it was so well received,” she said. “Joe is one of the best directors in the area to work for. He really is, because he trusts his actors. He trusts you. He’s seen you do stuff. He’s directed you before. He trusts me to get it done and get it done right, and entertain the crowd, and that’s nice.”
