Baths always did help Link to think.
"Yeah.... maybe I'll take a bath or something... I need to relax" Link sighed while looking at his somewhat plumper frame. After some searching, Link found a royal bathrobe and pulled it on. It actually concealed his chubby body, which was a relief.
He snuck out of his room and made his way down the grand hall. He could feel the layer of chub bouncing while he walked. Lucky for him, his reputation as a hero meant that the guards weren't obligated to guard him, so the hall was empty. He finally found the bathroom and opened the door. A light steam filled the room, and the always warm bath bubbled in the centre of the room. Link locked the door and walked in.
"Can't have anyone finding me like this..." Link said while dropping the robe. He pulled off his hat and settled into the warm water. The thoughts of his newfound chub faded a bit as he relaxed.

Ganondorf had just finished supper,and decided it was time to check on the hylians progress. He entered his chambers and pulled out the dark mirror again, waving his hands over it, he saw Link pulling off his bathrobe and hat. Sure enough, the hero had a small belly.
"Why would he be taking a bath at a time like this?" Ganondorf chuckled. "He's either not very bright, or hasn't noticed yet. Well... I'll make him notice." He began to laugh. Once he had finished, he prepared himself. Ganondorf chanted, and waved his hand before the mirror. The triforce of power began to glow on his hand again. "Time to become a hero of considerable substance, hylian."

Link was sloped low into the hot bath, he let out a deep sigh. What was he going to do to get rid of the new stomach? While he lay in the bath, he felt a tingling go across his body...this felt familiar, and it caused him to get up with a start. Then, he felt it begin again, the tingling gave way to a swelling feeling. Link looked through the surface of the water, and his eyes widened.
His slight stomach was bowing out, swelling. His pectorals were softening. His thighs and arms too! He clamoured out of the water to see what was happening. His body jiggled as he got to his feet. His loincloth was tightening, he looked down, seeing his belly and chest swelling. He looked in the mirror on the wall, his backside had grown considerably! He lifted his arms to see his sides. Love handles were growing on his hips, and rolls were bunching at his sides.
His once lean thighs were pushed together. His legs were thick now. His stomach was pushed out far in front of him, and folded at the hips a bit. His hips had widened, and his tight chest had become round and soft. Link attempted to run to the mirror, but was forced to waddle, making his body sway and quake. He examined his face. His once strong jawline was replaced by a soft rounded curve, and his cheeks had filled out. The fattening soon stopped, leaving Link at just under 300 pounds.
"Oh no! I knew I shouldn't have taken that bath! What am I going to do now?" Link groaned as he grasped his gut... he was very uncomfortable in his too small loincloth now. Then a thought occured to him... what if this happens again? How big would he end up?! "I need to fix this!"
He grabbed his robe and tried to pull it closed, but his body was far too big for it now.
----------------------------------------------
Ganondorf sat back in his chair, laughing. The hero was getting pretty husky...
"Now, what to do...." Ganondorf scratched his chin. "I suppose I could let him squirm a bit and try to find a way to slim down...." He grinned "Or I could put some pounds on him right now..."
