My Beloved pet, Azurelos, has passed away and forgot his name.
A potion of resurrection and maybe even a name tag for my little Blue Bolt, please?

I sent you a resurrection potion ^^ You shouldn't need a name tag as when you revive your unnamed pet it'll ask what you want to name it~

Hello, I'm sorry to hear about your pet ;o; 
You can get a Resurrection potion by doing to Resurrection quest, it's found under:

Games> Quest > Resurrection Quest.
The Quest will walk you through all the items you need 
You can also buy them from other users! 

Name tags can be brought from the cash shop or from other users
