For the first prompt I would like to see the dragonets of destiny decorating the main hall there are no preferable costumes or anything except maybe starflight getting scared by a talking one for the second one I would like to see the jade winglet trick or treating on jade mountain and maybe a part where qubli is trying to scare winter for the 3rd one maybe the main characters of arc 3 going through a graveyard with a bunch of dead dragons from the series graves and maybe Luna sees freedoms grave and in the background bumblebee is summoning Satan to turn swordtail into a cookie
