I'd use my آگ کے, آگ bending to make s'mores! And I'd keep them all to myself! I'd use my airbending to fly (or Airbender whatever) over to the mall where I'd buy every piece of Frozen merch they have! I'd smash all of the plastic things with my earth L ended and everything that can't be smashed gets lot on fire! Then I'd go to my دوستوں house and tell him I'm an alchemist now (we both like FMA). I'd دکھائیں off my awesome bending skills and pass it for alchemy! Woo! But I can't be too selfish. I would go to countries where it's hard to find clean water and a) make ponds closer to where the people live and b) use my water bending to clean the water! This sounds like a good day, if ya ask me. I get to bend all the elements so I can destroy Frozen merch. (I don't like Frozen) and make snores then go to my دوستوں house and convince him I'm an alchemist and then I can actually do something hat the avatar would do and help people! Yay!!! Tbh though if get bored of these powers in about 2 months.
Make an ice قلعہ and then design some weapons out of ice too. Water can make so much textures and it feeds my need of creation <3 Still, I guess I would find other uses for the rest of the elements. TOO MUCH POSSIBILITIES
