Since my char is a summoner... I would immediately summon a legion of carbuncles. Learn how to make them look like cats and not carbuncles. Live with my aether cats.
Fly all around on my birds. Inspect my new tall, male body and long ears. Walk around as a very tall person for the first time in my life. Tell all the NPCs I hate like Thancred that I hate them.

Finally, drink and party with the Moogles until I die of Kupo nut poisoning.
