Where I can get a cool iPhone 5 case?

I have an iPhone 5 and I have a case that is black with gold studs. I like it but it is getting old. I want to know if there's a place where I can get a case (preferably online) that is CHEAP- under $5 is great, under $10 is acceptable.
Me and my best friend both have iPhones and would love to get matching phone cases that say best friends but here's the thing- she has the 4, I have the 5.Is there a website where I can get matching ones for different phones?
I love the show Big Bang theory and I would love a case somehow relating to it, but the only ones I can find are too expensive.
I'm a female and I also love cats and dogs. If that helps.
Amazon and etsy are my two favorite sites for buying things so if you find one on there that would be awesome.
The case doesn't have to be high quality whatsoever. It just needs to be able to protect my phone from scratches and the occasional drop.
If you can answer this you are amazing. I know it's confusing! If you love your phone case but don't know where it's from tell me everything you can about it and ill find something similar.

My dog ate a fairly large earring?

It isn't that big it was a larger than normal stud, about the size of the circle button on an iphone. She ate it and we gave her peroxide or whatever and she threw up but she didn't throw up the earring. Will she be ok?

I dropped my iphone 4 in water and it works?

This morning while I was getting ready for school and I dropped my iphone in the toilet! But luckily retrieved it after half a second or second. I immediately tapped all the water out with the nearest towel and shook it out for 5 mins. I even googled things on it, and it was working perfectly. (later i found out you're not supposed to do that) And since I didn't have rice, I left it in couscous for 8 hours. I just came back home and everything is working fine, like perfectly. Will it start messing up in a few days? And should I take it to get fixed right now even though it looks like there isn't anything wrong at the moment?
