	In 1985, the BJ Birdy character was described as "lovable, irascible, curious, impudent, mischievous, and often the victim of his own impulsiveness." Much of the routines were improvised. "B.J. is a reaction character. He's a fan. He wants to know what's going on. He'll duck behind a dugout and then pop up again. He does what a lot of fans would do if they weren't so reserved." The costume had "perfect vision", and was said to be quite agile.
