Unlike in the original server, you may change the class of an object by Fiddle>Modify Object. Once set, select a different object and then click back to see changes. Note that any additional fields in the new class not already present on the object will be set to blank or zero, which might NOT be a sensible default.
If you select a class that is unsupported by the client or server, the object will appear to vanish, but will till be in the database. If you have it in your pocket, or hands, it can upset your client because it thinks the slot is empty, when the server knows it is not. So, please do not do this!
