Please find below code:
SObject[] queryParentObject = Database.query('SELECT Id, CaseNumber,Status, (SELECT Id, Name FROM Attachments) FROM Case');
for (SObject parentRecord : queryParentObject){
Object ParentFieldValue1 = parentRecord.get('Id');
Object ParentFieldValue2 = parentRecord.get('CaseNumber');
Object ParentFieldValue3 = parentRecord.get('Status');
// Prevent a null relationship from being accessed
SObject[] childRecordsFromParent = parentRecord.getSObjects('Attachments');
if (childRecordsFromParent != null) {
for (SObject childRecord : childRecordsFromParent){
Object ChildFieldValue1 = childRecord.get('Id');
Object ChildFieldValue2 = childRecord.get('Name');
System.debug('Case Id: ' + ParentFieldValue1 + ' Case Number: ' + ParentFieldValue2 + ' Case Status: ' + ParentFieldValue3 + ' Att Id: '+ ChildFieldValue1 + ' Att FileName: ' + ChildFieldValue2);
}
}
}
Hope it may helpful for you.

I tried below query in workbench which retrives Case's attachment only:
SELECT TYPEOF Parent WHEN Case THEN CaseNumber END FROM Attachment WHERE ParentId IN (SELECT Id FROM Case)
SELECT TYPEOF Parent WHEN Case THEN CaseNumber END FROM Attachment WHERE ParentId =: someCaseId
