Many people ask if Bumi isn't actually Sokka's son and Katara had given birth to him by mistake.
Also, it's punny.
Been working on this for days because I got so lazy to finish. I played around with the designs of Katara, Aang, King Bumi (who looks like Bumi 2 anyway), Ikki, and Meelo since we only have the oldie versions of Kya, Bumi, and Tenzin. I stuck with cel-shading to be faithful to the show. Kya and Bumi's clothes I sort of just went with random pieces until it looked traditional-y but modern-er than ATLA generation's clothes and Tenzin's attire is a mix of Aang's and Meelo's monk robes.
I honestly can't believe no one's thought of this yet. It came to me after having not slept for 2 days, which is usually when terrible jokes like to pop in and say hi.
