Just an idea, but thought it could be cool if possible. I imagine new types of baits that match each fish category, and while using them, you would be able to see the actual fish, as opposed to the shadow.
This would only work for the type the bait matches, so while all fish types still spawn, if you’re using the special item bait, you’d be able to see tyres and gems to pick them out.
These baits would be expensive, maybe 10,000 for one was a price I thought up, this is to make sure players aren’t using this for every type of fish, only the ones they need to complete the collection book. Curious what people think of this idea.
