The Squishy Button can be pressed forward and backward, left and right, and wiggled around. Hold down the Squishy Button, then let go of the Squishy button to jump up. Hold down the Squishy Button and move it left or right as you let it go to jump in the direction you moved the
button.
Press the Squishy Button a lot while on the Room Screen to give your Punirunes a lot of squishes and make them happy!
NOTE: Avoid scratching the Squishy Button with your nails or pulling it too hard. Just squish it gently with your fingertips!
(The button is made of soft materials, so you could scratch the surface.)
