Visible crew/equipment: When Newton is playing with the robot arm and the piano you can clearly see wires attached to the top of it controlled by the puppeteers.
Continuity mistake: In the battle scene at autobot city, Megatron orders Soundwave to jam the transmission that Blaster is sending to Optimus Prime. When Soundwave ejects Rumble, Frenzy, Ravage & Ratbat we see them flying through the air transforming simultaneously and and both Rumble & Frenzy are coloured the same (red & black) when Rumble is supposed to be purple.

Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Continuity mistake: When Baby Secret Bear and Baby Tenderheart jump on the rainbow to leave the cloud boat, you can see their "tummy symbols", which they have not yet received. The symbols disappear as they are sliding, then when they reach the bottom of the rainbow, the symbols are given to them for the first time. (00:06:35)Kathy Tjarks
Continuity mistake: The film is supposed to take place in 1917, but several of the german soldiers our heroes encounter are armed with Bergman M18 sub-machineguns which didn't appear until a year later. To make things even worse all the guns comes with a magazine-type that didn't appear until the mid-thirties.
Continuity mistake: When Tiger and Fievel are doing their musical piece, Tiger wipes off the mirror and they appear the same size. When he lays out in front of the mirror, singing the line "We'll be there to pick each other off the floor", he places his head next to the cage bottom, still laying on the floor between them. In the mirror, however, that cage bottom is not reflected at all. (00:57:30)Garlonuss
Continuity mistake: The group who set out for Flutter Valley are chased by Ahhg the giant spider after tickling him and slipping away unnoticed. As they make a dash towards a nearby cliff, Gingerbread (white Pony with purple, pink and blue hair) and Baby Lickety Split (light purple with pink hair) have somehow joined the group, but Baby Lickety Split should be with the Grundles and Spike and Gingerbread should be back at Paradise Estate.Blue Phoenix
Continuity mistake: In the scene where Dr. Dawson and Olivia are seeking Basil's help at his house, Basil sits down and starts playing the violin, holding it in his right hand and having the bow in his left. When Basil the stands up in another shot, he is holding the violin in his left hand (like it's supposed to be) and the bow in his left.
Continuity mistake: In the scene where Steph is in her second show, there are at least 2 different horses. The manes and tails go from being braided to being unbraided. Also, the breeches change from grey to beige. One of the horses before her round, a chestnut, has one sock, then none, then three, etc. There were multiple (I counted at least 7) horses that played the part of Lightning, who was supposed to be registered with the Jockey Club, which is the Thoroughbred registry. Most of the horses that played him were not even close to being Thoroughbreds.
Other mistake: In the first scene when the hurricane has passed and Pazu and Sheeta land on the cloud, Pazu twirls Sheeta around until they are almost off the edge of the cloud (his toe actually is on the edge of the cloud). But in the next few seconds the direction changes and they end up back on the cloud.
