This is a new line of toys called Osushi Sentai Shirada ($11) , aka sushi transformers, that transform from harmless pieces of raw fish into fierce battle warriors with a few flicks of the wrist, and there are more pieces available to create that ensemble lunch special of choice, which will undoubtedly transform into a fearless tribe of fierce fish-smelly warriors.
Note: There is no sign of the Miso soup warrior as of yet.
