Cynthia Nordstrom had one question for the creators of the popular Disney Channel series ''Phineas and Ferb.''
''One boy has a triangle head,'' Nordstrom said. ''What is that?''
Nordstrom had vested interest in the question. As a costume designer for Feld Entertainment, she was entrusted with translating the animators' vision on stage for ''Disney's Phineas and Ferb: The Best Live Tour Ever,'' which comes to the Covelli Centre for two shows on Saturday.
Dr. Heinz Doofenshmirtz plots something dastardly.
Nordstrom has created costumes for Ringling Bros. and Barnum & Bailey Circus as well as for several Disney on Ice productions. What made working on "P&F'' unique is that this is the first live production featuring the characters from one of the cable network's most popular shows.
''What's exciting about this is no one's ever done it before,'' she said. ''It's a hot TV show. How do we take it out on the road but also keep the characters childlike ... I wanted them to be able to do anything, just like on the show.''
Crafting costumes for a productions like this involves balancing aesthetic and practical concerns. The costumes have to recreate an animated world for a young audience, but they also have to meet the demands of a traveling company that does multiple shows on the same day.

''I go to fabrics that stretch and can be laundered regardless of where it was,'' Nordstrom said. ''They have to last and be maintainable by a crew. They can't be too fussy.
''I try to vary materials. I like to use color and texture to mean something. This one is all about bright colors and simple surfaces.''
That triangle head made Phineas one of the most difficult characters to reproduce, she said. ''I thought Buford would be, but he became very easy.''
The stage show is built around some of the popular songs featured on the cartoon. The characters perform ''Gitchee Gitchee Goo,'' ''Squirrels in My Pants,'' ''Backyard Beach,'' ''Busted,'' ''Today Is Gonna Be a Great Day'' and ''Summer Belongs to You'' as well as ''We're Gonna Put on a Show,'' which was written specifically for the live show.
And the maneuverability of Nordstrom's costumes becomes important as the cast members must execute acrobatics, a Broadway-style chorus line, a Bollywood production and the dance moves for a reggae hip hop party.
Of course, the show also include the stepbrothers' pet platypus, Perry, who will turn up as his secret identity - Agent P - to thwart the latest plan by his nemesis, Dr. Heinz Doofenshmirtz.
Nordstrom spent the last four weeks of the rehearsal process with the cast tweaking the costumes and troubleshooting so the touring staff will be prepared if anything goes wrong.
''They would never reach out to the designer (on the road),'' she said. ''During the tech / dress process, that's when you're ironing out all of those scenarios.''
In addition to the 15 performers on stage, the touring stage includes 10 crew members, four truck drivers, four staff members and 13 concessions workers.
Nordstrom just finished work on the next Disney on Ice production, which involved more than 200 costumes to create characters from three Disney features, including the latest Disney/Pixar film ''Brave.''
''You're always learning new ways to use fabrics and different applications.''
