Isabella "Izzy" Fuentes is the best friend of Tripp Campbell in I'm in the Band. She is a huge fan of Iron Weasel and many other rock bands. Izzy can sing very, very well. She once sang back up for a gig. She loves laughing at people's crazy dreams, espically Tripp's. She has brown hair and black eyes. The things that Izzy collected from Iron Weasel are a lock of Ash's hair, a half-eaten churro from Burger, and Derek's toenail clipping. As Tripp would say,"weird, weird, and crazy weird."
