One night, when Toph was walking back to the main hall of the Airbending temple, she noticed a small whole in the wall. When, she looked at it more closely, it gave her a great idea. The night Zuko, pleaded to join the group, he burned her feet, and she was REALLY blinded for a whole day.
Later that night, she went to Zuko and asked, "Hey, Zuko, do you think you could help me with something."
"Sure," Zuko replied.
After dinner Toph led Zuko to the hole and said,"I was playing with my bracelet and I threw far into that hole and for some reason, I can't bend it out or see anything in there."
"Well, that's strange, but I 'll get it," he said, crawling into the hole.
He kept crawling until all that was only his feet were sticking out."Hey Toph, I think I'm at the end of the tunnel and I don't think its here," Zuko said.
"Right," Toph said, smiling mischievously, "This is for burning my feet."
"What is, Ah!" Zuko yelled as Toph earthbended the hole shut around his body, restricting his movements so much, that all he could do was move his feet, a little.
"Now, what to do," Toph said, grinning evilly.
