Fish Flingers is an activity where you can earn lots of fishing experience. If you know what a star is or an evil tree, Fish Flingers is the fishing equivalent.
What you do is find a fishing area, either on the docks, on the beach or inland at the river. You select a hook, bait and sinker(s) with the goal of getting your ability to fish to 100%. Change the hook, bait or sinker(s) until you get to 100%. You have 15 minutes to find the perfect tackle.
Also, within that 15 minutes, you are catching fish and you are givien the total ongoing weight.
How much fishing experience you earn depends upon the total weight of the fish you caught plus the tackle percentage (hook, bait, sinker). There are a variety of fish to catch.
You get a certain amount of tickets, maybe 10, per week by the Fisherman. You redeem one each time to participate. If you use up all your tickets before the week is out, you have to wait until the next week, or win a free ticket on the Squeal of Fortune.
Have fun with it!
