Go to http://aquapets.wikia.com/index.php?title=Special%3ALog&type=delete&user=&page=&year=&month=-1 and find the files you want to restore. Then go to w:c:aquapets:Special:Undelete and write in the names of the files you want back. You should be able to follow the instructions from there to recover the old files.
