Continuity mistake: When Toad General calls for the council's attention and announces that Bowser found the Super Star, note his shirt buttons. Then, when he says that the Kongs will never agree because their mad king doesn't make alliances, Toad General's shirt is backwards, his buttons are on the opposite side. (00:24:55 - 00:25:35)
Revealing mistake: Just as the first credits roll, when the cheerleaders dance, check the African American, Caucasian, and most noticeably, the Asian American people behind the team. They are blatant, creepy-looking, unrealistic CGI characters. (00:01:18)
Continuity mistake: In the beginning scene where Dog is in his apartment, there is a loudspeaker to the left of his TV that constantly changes design. Some examples: there are either one or two wires plugged into it, the wires are either plugged in near the top or middle of the back side, the front and back are either metal or wooden, and the top and bottom of the front side either point diagonally or don't. (00:01:55 - 00:02:46)
Continuity mistake: On the bridge, when Freddy grabs both cars and stops them from falling down, the driver on the left pops his head out the window, then back in, and then he pops it out again. A mere frame later his head is inside and his body is in a different position with both hands on the wheel.
Continuity mistake: Scott hugs his daughter and caresses her face while she holds his wrist. From the opposite angle, her hand is gone.
