popup when trading a new dec 18th pet

[test.tube.bunny]

if an account is on the newer side i think it would be good if there was a popup before trading away a new dec 18th pet warning the player that the pet could be very valuable, and urging them to look up their pets rarity to make sure theyre getting a fair deal, to help protect newbies against ninja trading. i know there are announcements on the front page and forum threads but ninja trading still happens a lot, unfortunately.
