If you're having trouble with your mine cart in Animal Parade, there are a few things you can try to get it up and running again. First, check to make sure that all of the parts of the cart are in good working order. The wheels, axle, and frame should all be in good condition. If any of these parts are damaged, they will need to be replaced before the cart can be used again.
Next, check the track for any damage or obstructions. If the track is damaged, it will need to be repaired before the cart can be used. If there are any obstructions on the track, they will need to be removed before the cart can be used.
Finally, make sure that the power source for the cart is working properly. If the power source is not working, the cart will not be able to move.
If you have tried all of these things and the cart still isn't working, you may need to take it to a professional to have it repaired.
