Continuity mistake: When Juni and Carmen reach the door to the Super Guppy, Felix puts the locating device down on the black bag with both handles down and then leaves. However, when Carmen retrieves the locating device the left handle is upright, though nobody touches it. (00:21:25 - 00:22:30)
Continuity mistake: Robots Juni and Carmen appear, after Gregorio and Ingrid ascend into the opening above, and as they run up the wall and flip over a huge green work of art hangs on the corner wall at the left side of the screen. However, when robo-Carmen taunts Juni a smaller pink frilled work of art hangs on that very same corner wall. (01:13:20 - 01:14:40)
Visible crew/equipment: After Carmen and Juni arrive at the safehouse, Carmen puts a small packet into the rehydrator and soon removes a burger and fries. When she closes the rehydrator door two crew member's reflections are visible. One is to the left of Carmen's reflection, on the glass window of the rehydrator and the second, who has very long hair, is reflected on the upper fry pan in the wall. (00:28:50)
Other mistake: Near the end of the movie, Juni watches the start of the Floop's Foogles show. Yet the clock on the TV showed out the time to be 10:15 - 10:20.
Revealing mistake: When Carmen and Juni fly into the clothing store, the door opens for them, but when the Thumb Thumbs get to the door, the door doesn't open for them. (00:42:10)
Continuity mistake: When Carmen yells, "You're strong Juni!" after the extreme close-up of Juni's fist, in the next shot a specific piece of loose painted plaster falls from the top left corner of the hole, as his fist hits. However, in the next two shots of Juni, that piece of loose plaster is actually back up on the wall!! (01:15:15)
Continuity mistake: The robot children pass Carmen and Juni, who are hiding in a doorway in a specific area off the long corridor. However, when Carmen and Juni decide to follow the robots to try and find the dungeon, they run out of their hiding place from a completely different area along that corridor. (01:02:25)
Continuity mistake: When Carmen and Juni are getting into the boat/submarine for the first time, Juni can be seen sitting down in one shot, and then sits down again in the next shot. (00:21:50)
Continuity mistake: In the kids' room, when Ingrid approaches Juni to remind him about the wart medicine, Juni's red and yellow cars are on the blue dresser behind Ingrid. Then when Ingrid finishes telling the spy story, as she says, "Trading espionage for parenthood," the cars' positions differ, and when Juni says, "It needs monsters," they change position again. (00:01:05 - 00:06:35)
Continuity mistake: When the kids in the Guppy zoom towards the boat, in the first shot facing the man in the boat, the large distinct building is clearly visible on shore in the background. Yet, in the following shot facing the front of the Guppy as they actually fly over, that building on shore is now behind the Guppy! Then in the next shot, at the same angle as the first, the shoreline is completely different. (00:23:30)
Revealing mistake: Throughout the shots of the corridors in Floop's castle, the many works of art, light fixtures, etc., are repetitive, despite the fact that they are supposed to be different corridors. Although one can say there are identical works of art and so forth, in the multitude of corridors, however even the painted uneven surface of the walls surrounding the art, etc., are perfectly identical.
