A bottle of fish bladder stoutier is an alcoholic drink acquired by prying open a sealed crate in the Skullhorde, south-east of the bank boat. Doing so requires a crowbar in the inventory, which in turn requires completion of Prying Times to obtain.
Drinking the bottle grants 75 Sailing experience, and spawns Dinky the drink troll, who can hit up to 50 damage with an attack speed of 4.
As such, players are highly recommended to activate Protect from Melee before drinking this bottle, and make use of the nearby Bank boat to get into combat gear.
