Continuity mistake: When Pistachio is dressed a the cherryman, he spits his cherries at the henchman. He turns and spits one cherry, hitting one henchman right on the forehead. The henchman then falls backwards into the swimming pool, causing a huge splash. But in the very next shot, the water is totally still and the henchman seems to have disappeared from the pool.

Plot hole: When Pistachio and Jennifer go to the toy convention to find Bowman she says her name is Barbara, and Bowman invites her to his house. When Pistachio comes looking for her at the door (as the German Guy and the Snobby English Guy) he says he needs to talk to Jennifer Baker. Wouldn't he ask to see Barbara instead of Jennifer? Also Bowman knows her as Barbara and didn't say anything about him calling her Jennifer.
Continuity mistake: When Grandfather gives Pistachio the "nest in a box," the shots change. One is the tables with the red tablecloth, which we see at the beginning. At a different angle, we see tables with tan tablecloths. (00:34:32)
Continuity mistake: In the scene where Mr. Peru is asking the waiter for things that he doesn't have, the shrunken head in his hand disappears between shots. (00:49:49)
Continuity mistake: When Jennifer and Pistachio are looking at the photos in the restaurant, in a wide shot Pistachio holds a photo, and on the table in front of him there is an envelope, but no photos. But in the next close-up, Pistachio throws the photo he was holding onto a pile of photos on the table, which were not there in the previous wide shot. (00:54:05)
Revealing mistake: When Pistachio grabs hold of the handles on the weight machine, they pull him forward and he goes flying into a wall, and his feet kick in and hit the wall making two holes. However as he flies towards the wall, you can see that the wall where he will make the holes has been weakened. (00:06:10)
