Tuck and Roll are Hungarian twin pill bugs. They occasionally argue but are usually the best of friends. They act as cannonballs in P.T. Flea's circus troupe. They are supposed to be the main part of the "Flaming Death" act, but their arguing and fighting results in the act going totally out of control and everybody being fired. However, they don't seem to understand this and remain cheerful even at the Bug Bar. They also appear to like the sound of the phrase: "You're fired!", since they continuously repeat it throughout the film after P.T. Flea says it to them, much to Rosie's irritation. They were both voiced by Michael McShane.
