Continuity mistake: In the scene where Chicken Little lends the alien baby, Kirby, his handkerchief, after Kirby blows his nose, it sticks to Chicken Little's hand. Chicken Little then wipes the hanky off his hand on to the grass. In the very next shot, the hanky has disappeared, and never shows up again.
Continuity mistake: Following Rodney's step from the escalator on the red pedestal he is being scooped into one half of a wire-frame globe/ball. Two halves now (the other one has Fender in it) form an intact globe. A safety bar with a 'wooden' middle bit (like those on rollercoasters) suddenly appears. After their journey, when the ball splits back into two halves, the safety bar, which previously had mysteriously appeared, now has disappeared.
Continuity mistake: When the Were-Rabbit jumps through the stained glass, the right ear is pointing to both dragon wings.
