Good use of the turn donk?

[Mister Z]

This hand turned out a little strange. I only occassionally raise with KQo but this table was pretty fishy. Anyhow, MP2 is slightly loose/aggressive and the other two players have been playing very fishy and are making the table very good. 3-bet the flop? Turn donk?
