Three in a row

I'm stuck in the bar scene on three ducks in a row. I found all the ducks, know about the numbers, but I don't where they go. Can someone help? Can't go any further.

Been forever since I played this but is there a shelf behind the bar? They might go there or I might not remember right at all lol good luck.

There are shelves behind the bar, but can't seem to make them stick even when I get the sequence of numbers right.

Thank you for replying and will try again.

They go in with the ducks that are already in the back of the bar. So the numbers on the ducks are 2, 3, and 4.
