What did you get from river

I HOPE MY SENTENCES ARE CORRECT.@_@

a four-panel comic, for harvest moon grand bazaar.
i use emulator to play this game.
and this's real, i mean in the game.
i jump into river when i'm free,
and sometimes you can find something interesting in the river,
but most of time it wouldn't give you anything, or only a empty can. (but you can try over again till it give you something.XD)
...why she would not catch a cold?

this's Gretel, Antoinette, and Sherry from Harvest moon Grand Bazaar.
