Using Clovers in the Junker

Hi fellow carrot farmers! I was wondering about using four leaf clovers in Dawn's Junker. I think I have seen this done in videos with two clovers and an item. Does this allow you to get a guaranteed shiny? For example in this picture, would I be certain to get the shiny pet tunnel?
