I was put up against Dark Crusader. The theme was to build a half-rahi half-toa. My opponent
Amphibian was an inventor and Toa of Earth. One day, while searching for supplies in a swamp, he slipped and fell in to the the waist-high depths. The murky water was heavily toxic and acidic and began to eat away at his legs. Franticly, he thrashed his way to the shore. The acid melted his armour and disfigured his top body. Worse things happened to his lower body. Growths started forming, his DNA changed, and his legs took a new form. He now had-well- frog legs. He could swim faster than even Nokama, could leap higher than any jungle Rahi, and of course, if they were cut off, they would grow back.
There we go. Good luck to Dark Crusader in this round. :)
This was probably my fasted build ever. It took me one hour.
