SCOTTSDALE, Ariz. -- TCU fans cranked up the Frog Horn and the Fiesta Bowl spirit Sunday.
Fans gathered at Greasewood Flats, where organizer Joe Jordan spray-painted a metal horned frog sculpture purple.
The Gibbons brothers, Tim and Tom, brought their Frogmobile converted ambulance.
Frog Horn keeper Jim Garvin sounded a few blasts of TCU's locomotive horn mascot to scare a Boise fan.
The Frog Horn also appeared at First Christian Church of Mesa Sunday morning, sounding the call to worship with what the Rev. Bill Jacobs described as a "joyful noise."
