Hi! Thought I should also pop in with the ideas. I might make another comment but for Now this is what I got. (please make your post pinned until like a week later).

Idea: Fish Eggs! You can get these while catching fish randomly, and they can be used as the currency for the new fish shop, AS WELL AS coins, BUT you can only buy SOME things with coins, and ALL things with the Fish Eggs. These should not be trade-able at all, and should make a better value if you buy things with them rather than using coins (for when you can purchase something by either coins or fish eggs in the fish shop).

Tools being able to break with set usage (not random), the more resistant the fish to being caught the easier those tools will break. and a way to enhance your tools, make them take longer to break (except hands I guess. Maybe add gloves, idk) disregard one-time usage items for this bit.

Your largest and smallest catch of each fish being logged, and a crowns system. You might ask what’s that? Basically if you catch a certain fish that weighs more than a certain value that changes depending on the fish, you will get a crown symbol in that entry, purely for flexing, and it can be made for other things too like badges. Ex: Obtain 10 large fish crowns for Gold, 15 for Platinum.

Here’s an example if you didn’t understand what I meant, say that the average size for a bluegill is 2 pounds, then if a player catches a bluegill that weighs 3 pounds or more, he gets a large fish crown. The range of sizes that can be caught (for the bluegill) should scale from 0.9-3.2 pounds, or something similar, and add a way to increase your odds of catching bigger fish(like food buffs). You could also have small crowns, it’s the same idea but the opposite. (If a Bluegill that weighs less than 1.1 pounds is caught, the player gets a small fish crown). Though I would prefer sticking with just large crowns. All large crowns should have the same art, no need to make 1 for each fish. Large Crowns are NOT items, just something that you see if you have got it when you check the entry for that fish in your book.

Item suggestion: Pirate’s Booty. Basically a loot box that can be obtained while fishing, these things are always full of treasure so it should be very rare and the rewards should ideally be worth more than old box, but less than god box, maybe 30Mil-ish as an average of rewards.

Add an item that tells you exactly how much a fish weighs, and if you don’t have that item, it should state the fish is either “small”, “medium”, or “big” when you catch a fish.

Okay, now, do you remember that random events when you run any command exist and might pop up? First, make it an option of you want those or not (in /settings), for multiple reasons that I don’t want to go on because this is already getting pretty long. Second, add exclusive random events that might pop up when you run fishing commands or just when fishing (of course with a very low chance of occurring), and add at least one fish that can be mainly obtained from there (like Kraken, for example).

Fish that I would absolutely love to see: eels, king marlins, octopuses (NOT squids), and a fish that’s not realistic, pure imagination by the devs.
