This is a training toy for dogs.
You can put a treat (~1cm size) in the hole at the top that will be dispensed when the button in pushed.
(The plugs probably don't matter where you put them, but the one of them is just slightly shorter)
If you use the optional PTFE tubes so it slides better:
Slowly insert the insert into the bottom part. If it doesn't slide free, sand/cut the outside of the tube a bit until it slides with little resistence
