I'd probably raise on the backside on third street, but the call is fine too. I would strongly consider raising fifth. The bettor might have trips, but he might also have a four-card low or maybe two pair, in which case you're in excellent shape, and I think you're a pretty solid favorite over his range. Definitely raise sixth. The bettor probably has two pair at most. 77 didn't raise, so he shouldn't have trips. You do. Get your money in there. The river is probably worth raising as well.
