You decide to spend a little longer in the sun, it feels so good against your smooth, green skin.
After a minute or two of standing in the sunlight, you begin to feel an odd sensation in your toes. Looking down, you see that your feet are turning brown and are also splitting apart! Your toenails begin to pop off, as your toes- which now reach to your ankles and have replaced your feet entirely, lengthen out and become more tendril-like. You try to turn in the direction of the castle but end up falling into the pool of water due to your strangely shaped toes. You quickly begin to freak out, disgusted at the proposition of drowning in half a foot of water and at how Elthissa has technically lied to you, but you soon come to the realization that plants don't need to breathe and calm down. Slowly, you push against the wet soil with your palms, the surface is slippery but you manage to get back to your feet. Looking down, you remember that you don't have feet and also realize that by getting up you have only pushed your misshapen toes into the ground.
You can feel that your toes, which now appear to be roots, have separated into many dark brown tendrils, which have begun digging into the ground at a very rapid pace. Carefully, you try to raise one leg, but are surprised to find that you cannot move your roots at all, aside from a small wiggle. The part of yourself that would be considered roots spreads all the way up to your knees as you struggle in the ground.
