Chester trembles at the sheer sound of one since one attacked him once and no matter how fast he ran, it wouldn't let him go, so now when he hears one, he runs to hide (the house protector...Right? ). Giz on the opther hand, searches for them. She LOVES the sound they make and all you have to do it touch one and she is right there to play with it. Her favorite thing to do it to find one at night when the light go out and play, PLAY, PLAY!
