Ducking was a new feature that was added on June 24th, 2010 with the addition of 6 new items to the shop. The creators of Transformice claim it was just a "cute" sprite animation, and many believed for it to be a glitch. But new uses have been found, which seem to have been intentional.
- Tap or hold the down arrow.
- Hold Right or Left Arrow depending on which direction you would like to slide
- Practice/Timing is required
- Serves no practical purpose.
- Contrary to popular belief, this action does not change your hitbox on either Map 63, Map 64, or Map 65, meaning the windmill will still kill you.
Dancing is a "feature" that came along with ducking. Different types of dancing have been discovered by players shortly after the patch, such as Moonwalking and Ducksliding.
