Trivia

 * The robot appears to be assembled from junk. This is a typical motif with many of Crazy Dave's inventions.
 * This is referenced in its name, officially being Junkasaurus.
 * When there are four players cooperating in Infinity Time, the robots will be colored (in order from players 1-4) green, blue, red, and yellow. These four colors correspond to the colors of each Zone in Infinity, excluding the Rainbow Zone.
 * Both of the robots are the only characters that cannot jump.
 * The Charge of Insanity may be a reference to Crazy Dave, as "insane" is a synonym of "crazy."
