Happy Ghast
When the Happy Ghast has no players on top of itself, excluding passengers (checked every tick), it will stop moving for half a second. If there are also no passengers, the Happy Ghast will stop moving for two seconds instead. If a player rides a Happy Ghast with no passengers or players on top of it, the Happy Ghast will be able to move immediately. This behavior is implemented by the still_timeout NBT integer field, a value counting down from 40 to 0.
