I personally prefer the V4.5 to the V5.
I really didn't like the V5 much because I didn't like that you had to take care of 3 Tamagotchis as opposed to the usual one.
Also, I didn't really like the games, & I don't think the TamaTown for the V5 is as good.
1) Live Like We're Dying - The Script.
2) W.A.M.S - Fall Out Boy.
3) Patience - Take That.
4) Give Me What I Want - Kids In Glass Houses.
5) We Are Broken - Paramore.
6) Heavily Broken - The Veronicas.
7) Born For This - Paramore.
8) Barriers - David Archuleta.
9) Don't Let Go - David...
Hm, most WalMarts sell Tamagotchis, it's strange that your one doesn't.
Maybe you could ask someone there if they're still going to be selling them anymore?
If not, maybe you could order one off the internet, perhaps on eBay? :)
