Drowning
Drowning was a potential cause of death that would occur when an individual was submerged in water for to long.
Probably since drowning isn't particularly graphic to actually display, there have been quite a few instances of ponies, humans and dragons nearly drowning to death throughout the franchises run, possibly more than any other cause of death. Some instances portrayed as lighthearted, while others were rather dire.
