The hard-shelled creatures of the Arthropods were definitely make for an interesting transformation. You turn to the page to find yourself swamped with all sorts of choices. It went beyond just insects, it also included Spiders and Crustaceans. There was even some ancient insects in the list!
You took the time to read over the different creatures.
A butterfly looks like a good start. You imagined floating on the wind and sipping sugary sweets from flowers.
A praying mantis is also interesting. The sharp eyesight and lightning quick reflexes would be yours to master.
Or a Spider. They tend to scare people, but you wondered how it would be from a spider's perspective. Plus you wanted to test your web weaving skills!
Your choice made, you took a deep breath and say the command word.
