Phineas and Ferb material or fabric?

My son is wanting a Phineas and Ferb themed room. I have looked everywhere for queen size quilts and fabric, but I have not had any luck. I have also looked at Perry the Platypus stuff, and cannot find anything. Disney carries the TWIN size comforter set, but I need a QUEEN.... I decided I could make him a quilt but I cannot find any fabric to do so. Anyone know where I can find some online?
