Birthday idea

For my friend's birthday I got them a Lovely Cake (it actually shows up in-world), and shot off a bunch of fireworks. If that someone is special and you still have it sitting around your inventory, have them join you for a picnic with a Romantic Picnic Basket.

If you're looking to send gifts in the mail, you can try your luck at Blingtron and mail them an Eternium Rose and any mini-pets that they don't already have.
