3/6 I miss vs donk, who calls anyways?

[AAismyfriend]

SB is a big donk, but I haven't played long at the table so no solid reads, but he's been doing fishy stuff like limping button, and open minraising, and just seems overly loose. Does anyone ever call here on the river getting these odds? He instashoved river fwiw, and also instacalled flop/turn.
