The bailing buckets are a necessity for success in the Fishing Trawler minigame, so yes.
Those 11 buckets at the end that almost got excluded have probably saved me on many trips out on the great deep sea.
The 1813 buckets with green stuff in them contain ectoplasm-slime and are just the thing to level up your Prayer skill a teeny-tiny bit faster, so they've probably saved me from death by despair.
(At least until I could upgrade my player-owned house with an even better chapel so I can train even faster there. These days they probably wouldn't really help all that much.)
Most of these buckets have also probably held supercompost at one point or another, which is a godsend for the Farming skill.
That's a massive time-sink since it takes half an eternity for plants to grow, and if they die, TOO BAD NO
FOR YOU!!
Plants are thisandthatmany% less likely to die if you add supercompost when planting however, which means I might actually be able to reach 99 in that skill before the game shuts down/I die.
They truly are the unsung heroes of the game.
