Kingdom Hearts MIssion 45 Hlloween Town

I am seeking anyones help on this mission. I am stuck in the graveyard with the floating blue dog who you are supposed to feed the bones to. I can get the two balloons and beat the ghosts that come out then I feed the dog a bone and he circles a tombstone and stays there but I am unable to do anything to find the heartless after this. Am I missing something because I am stuck. I have tried hitting every tombstone and have found one heartless in the back corner. Any help will be great!!! Thanks ahead.

Try jumping up and hitting A repeatedly around it. Can't remember this one.

Anandjones right, sometimes you need to jump to make the target box appears. Press A and the heartless will appear.

Jump and quickly press A when u see the green box.

Also it's not mandatory to feed Zero if you can find the hiding spots yourself.

Thank you to all who helped I have made it by finally once I figured out I did not need to dog to find all the spots.Thanks again
