When Grumpy and Fun Shine Bear arrive at Anna's house, they crash the cloud car into the chimney, and the cloud car is gone. Later on when they show the front of the house, you can see the cloud car on top of the roof where it disappeared earlier.
When the toys attack the Care Bears team on the train, they appear strong, but a few minutes later when they try to explain themselves, all the toys are seen banged up and bandaged.
The toy train's caboose separates from the train, and then shows up later when the remaining team ride a boat.
