Skateboarding was first introduced to the hotel on the 27th of June 2011.
The effect can be bought from the pixel section for 139 pixels if you are HC and lasts for an hour. If you are not HC you have to pay 1 coin for the effect but it lasts for a week.
With the release habbo also added some achievement badges to entice people to use the skateboard.
You would probably want to use a booster to complete these badges.
