You have a feeling whatever's on that island is making all of you transform - and the only thing that can turn you back may be there too!
You hop into the water, dodging the coastguards trying to control the transfomed crowd - who are various weres and other creatures. When you are in deep enough water you start swimming at suprising speed, easily avoiding the coastguard by holding your breath and swimming underwater.
When you get to the island and wade onto the rocky shore, you find yourself walking upright again and your legs have grown longer and springier. "I'm walking upright again!" you exclaim "And I can talk too!".
Your confidence rising, you hop off to explore the strange island for a cure to your transformation and everyone elses.
