Continuity mistake: When Jiminy shows us Geppetto's place, there's a toy soldier next to a camel. From the opposite angle the soldier is now a giraffe. Seconds later, after he warms himself up, he looks at the window and there're two giraffes on the left, while the toys on the right are totally different.
Continuity mistake: Before Cricket arrives, Pinocchio watches the 8 ball. The wide angle shows the painted 8 on the opposite side to where he is, but from Pinocchio's blurry POV angle the 8 has swapped sides and it's in-front of him. note: This mistake has nothing to do with the already listed one about the 8 ball. This one takes place before Cricket arrives.
Continuity mistake: When we first see Gepetto inside Monstro's belly, he's wearing stockings and shoes. However, when Monstro sneezes and everyone escapes, he's barefoot, but there's no time for him to take them off.
Continuity mistake: When Jimminy falls down the pool hole, there is a card at the edge of the table. When he comes back up, the card has been replaced by a die.
Continuity mistake: The stones Cleo pushes up in her bowl while inside Monstro's stomach disappear in later shots.
