Right, see, I wasn't sure if I was supposed to be growing shell and multiple arms but keeping general human shape or if I was supposed to turn into a full on man sized mantis shrimp and then stay that way forever. Am I a Franz Kafka nightmare, or am I more like Kamen Rider?

Because if he's a shrimp full time it's going to be like that lion costume they use to celebrate Chinese new year is tromping through the halls.
