Ron meets Indiana Jones and the Lost ARK

The kids were helping Kali go through things in the attic when Ron finds a photo album and a hat and he learns that Kali and her friends the Adventurekids met Indiana Jones and when he finds out Ron gets excited and starts asking questions after questions.

But instead of answering the questions she sends him to 1936 to meet him and learn everything he needs and gives Ron the hat to show Indiana Jones he's a friend.

Ron then becomes Indiana's student on learning how to do what he does and many tricks.

And then they get a visit from some important people to find the Lost Ark before Nazis do.
