Link was caught off guard by the sudden tug on the line that he went
face first into the muddy shallows, fishing pole flying out of his hand.

“What- No- Wait-!” he couldn’t lose that! It was the best one he’d gotten! And it cost so many rupees!”

Quickly
he dived in  to grab the handle to the pole, only to be tugged again.
This was no ordinary fish- It had to be something massive. That’s it. He
was going to have to get this thing the hard way, and get his
rod back. Link pulled out a small knife and dove under the water,
searching for the fish, only to find two fishing hooks around a…treasure
chest? He, pulled off the hooks and grabbed it and came up for air.
Maybe there would be some big amount of rupees in it??

Marie, hearing a splash, reflexively looked up towards the river, but saw nothing. However, she did notice that there was much less pull. She relaxed. Finally, she could reel it in for the Repairman, no problem…

Speaking of the Repairman, he was still rather dazed, but he had risen to a standing position, gently swaying.

“Thank you, please come again…”

Marie watched him with concern as she continued reeling, until the hook came out of the water. It was not only bereft of a toolbox, but it was also missing the magnet somehow. Frantically, she shook her brother back to consciousness.

“Ugh, not so hard,” the Repairman mumbled, his eyes blinking back to normal. They sprung to the size of dinner plates when he caught sight of the empty fishing rod.

“What hap–”

“I don’t know, I reeled and then it fell…” Marie tried to explain, before falling silent. She hoped to triumphantly hand him the toolbox, but no such luck.

The Repairman sighed, shaking his head.

“All right, let’s just try it again…” He gave her an encouraging smile. “Not your fault…”

Then he spied (he presumed) a Hylian in the river.

“Uh…Hello there!” he called out. “Did you see a red metal box in there?”
