Ha ha, sorry, I probably shouldn't put the EAG photos first every year. It's a trade show for the amusement arcade industry so it's mostly amusement machines but also prizes for claw machines, bingo etc. Hence all the fakies (and occasional authentic plushies!)
Shaker Maker is a kind of model-making craft kit. It comes with powder which you mix with water and put into a mould, then "shake" it until it sets. I had one when I was a kid but failed dismally at making the model, took the mould apart and the wet powder crumbled (obviously I hadn't shaken it for long enough!) Never tried again!
