Done up like a kipper achievement

[Vulkan]

Anyone have any ideas how to achieve this? Cheers

During the course of the game you visit the fish monger's stall three times (The first time to get the spanner), he should have a different selection each time (Blue fish first, prawns and crabs, pink fish. I'm not sure if you have to hit all of the previous selection in order to flag it to change on the next visit). On the third time the fish should be all pink fish, hit the one closest to him a few times until he speaks and that should get you the achievement
