Dim is a large blue rhino beetle, with a green covered back, blue eyes, and a childlike nature, as seen when he sobs in pain after Rosie accidentally lashes one of his feet. He is also shown to be ticklish when some ant kids unintentionally tickle his thorax with their antennae while exploring beneath him. He is usually mothered by the black widow spider, Rosie. He is the largest insect of the circus troupe, and also the transport to Heimlich, Rosie, Tuck and Roll. He is big and strong but kind of cowardly like when Thud the horsefly scares his friends (although because Thud maybe was even bigger than Dim). Dim was voiced by Brad Garrett.
