This is the paper puppet I learned as a child, and have enjoyed making my whole life. Print and fold this 8.5 x 11 piece of paper into thirds the long way down the red lines of the center rectangle. Fold that long piece in half, then fold it back making a W shape. Here’s my paper Gomper puppet with added pop up tongue action in a video for you to see:
