There was a moment of silence before there was a glow that appeared around Ariel's leg.
That glowing soon spread all over her body and in no time at all, it seemed like she was starting to change.
Her legs came together and seemed like they were sticking to each other. It was as if they were forming a single limb with the way that they stuck together like that.
The skin that was on her legs started to change colour as well, going from the normal colour of skin to a greenish colour.
This was similar to the tails that the others in the room had.
This was the green of the scales that the mermaids had on their fins.
So her lower half was transforming back to its original shape as the potion broke the contract.
It didn't take long for her legs to take the form of a tail and she went from standing in the air bubble to sitting down at the bottom of the air bubble.
