Happy ghast should have dash ability

The happy ghast is so slow compared to normal ghasts and happy ghasts from the trailers and animations. It should have a dash ability just like the nautilus or something you can make to make them to go faster like being able to enchant their harness or when you hold sprint button they should go faster. i know it's main purpose is for building but that speed is kinda annoying for building and nautilus is also for building underwater why they are faster?
