Cabbage

Every since the Avatar was assumed dead Cabbage Man had an awesome time.
Everything was so peaceful (well as peaceful as it could be with the Fire nation in charge), the old man had even bought a shop for his cabbages.
Until King Bumi took back his kingdom and ruined his cabbage shop (maybe putting it in the shadow of one of the Fire nation's factories was a bad idea). Then everything was back to the chaotic streets with his stall.
All of a sudden Cabbage Man realized that this was something he could never escape from. He broke down crying.
