Long Glen Silver and the Pursuit of the Golden Fetchie! - S5.E19

Ruff's nephew Glen has been playing a pirate-themed video game on the Go Get It! website. Through this game he's somehow gotten into the Go Get It! mainframe computer, and discovers that they're hunting for something called The Golden Fetchie. Ruff wants to find the FETCHie first, so he sends the kids off to the island. And at Glen's request, he makes them dress up as pirates.
