I lost my new iPod touch 5th generation. I'm pretty sure someone took it ... HOW DO I FIND IT !?! HELP !

Did you have find my iPhone installed on your iPod Touch? if yes then you can try to locate it via iCloud. Also remember to change your iTunes password as soon as possible. Take a look at this link, http://support.apple.com/kb/ht2526

so you are PRETTY SURE that someone stole your ipod? hope your ipod is having a wi-fi connection and icloud on. otherwise you have no chance to find it.

so wat happens when i have my icloud account but no wifi can it still be tracked and would i have to pay for the tracking process and who does it

There is no way to track it except the old fashioned way like if you lost your shoe.
