25NL, 99 faces weird river bet from unkown

[Bowlboy]

I think my fold is ok here just curious if villain's got a busted straight or OESD often enough to call? Only 2 orbits with villain so nothing notable so far.

I probably call because you're gettin like 4:1 on your money but in general you'll be beat. Only hands you are beating: A4, 77, 88, 55. Are any of those hands betting this river? Probably not. I call for information alone but only because he donked 1.75 into an 8 dollar pot.

that bet is too small for me to fold to. The rest of the hand is fine

I really wanted to call. Maybe I should have. I feel that shorties would rather push here to get you to fold if they had anything I could beat, though even at 25NL the donks dont cease to amaze me. To me this just screams busted straight draw, a ten, or King/weak kicker. Maybe bad for image though. After this hand I got played back at on a couple of flops.
