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.

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: 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.
