Thumper bumpers are recurring interactive objects that have appeared in games such as Chick Flick, Twang, and Go Go UFO. They are generally fixed in the air and discernible as a circle with alternating border colours and a star in the middle. When a character hits a thumper bumper, they will bounce off it, usually at a sharper angle than a spring.
