The Fish Advisor: an insight.

TL;DR? The orange boxes contain the most important information.

What determines which fish is caught?

Rarity value

Each fish species in Toontown has a certain rarity value, which is just a number from 1 (very common) to 10 (very rare).

That number roughly determines the overall probability to catch it.

Locations

Note that some fish species can only be caught at certain ponds. Internally, this is accomplished as follows.

A list of locations is associated to every individual species. It consists of a main location and possibly further places:

At the main location, the fish can be caught with the rarity specified in the table above.
For each further location, the rarity value is increased each time by 1.

Have a look at the following example. A playground always includes all its streets.

Fish species	Rarity value	Main location	Second location
Pool Shark	2	Daisy Gardens (rarity 2)	Donald’s Dock (rarity 3)

Note that individual ponds can occur multiple times in the list. In this case, the fish in question can be caught with each of these rarities (see below how this works). The following examples illustrate this.

Fish species	Rarity value	Main location	Second location	Third location
Sea Horse	2	Estate (rarity 2)	Daisy Gardens (rarity 3)	Anywhere (rarity 4)
Florence Nurse Shark	8	Tenor Terrace (rarity 8)	Tenor Terrace (rarity 8)	-

Here, „anywhere“ includes the Estate and all ponds in Daisy Gardens. Similarly, Minnie’s Melodyland includes Tenor Terrace.

The catching itself

When you cast your rod, two independent dice are rolled.

At first, a rarity value is determined randomly. Higher rarity values are much less likely to turn up.
Once a rarity is chosen, the routine looks at all fishes you can catch at your current location and which have the determined rarity value. It then picks one of them at random, each equally likely.

Note that later rods have a slightly increased chance to catch rarer fishes. The following chart illustrates the likelihood that the several rarity values appear.

It may be the case that a fish has multiple rarity values for the same pond (see previous section). In this case it is a candidate for either of these rarities.

Have a look at the following example. This is a list of all fishes that can be caught with the gold rod at the pond in Elm Street.

	7	Olympic Pool Shark
	8	Shining Star FishArabian Sea Horse
	9	Siamese Cat Fish
	10	Siamese Cat FishAll Star FishHoley MackerelDevil Ray

Note that some species occur twice in this table – for instance, Amore Eel can be caught with rarity 1 as well as 3, while Siamese Cat Fish has rarity values 9 and 10.

Suppose the routine rolls a rarity value of 9, then you always catch a Siamese Cat Fish. If it rolls 8, you get a Shining Star Fish or an Arabian Sea Horse, each with 50% chance.

How do you compute the number of required buckets?

Using math and probability theory.

The value indicated in the statistics tables is the number of buckets you are supposed to fish in order to be 90% sure to have caught the fish you are hunting.

This does not guarantee that you actually have it then, but this event should be rather unlikely (it happens to one person amongst ten). Of course, if you are lucky, then you can catch the species already much earlier – this is especially true for rare fishes. If you are very unlucky, you may as well require much more fishing – but with every new catch, this is going to be more and more unlikely.

The indicated number of buckets does not need to be caught in sequence. In fact it is enough to catch them at any time in any district. Also, it does not matter whether you catch a different new species in the meanwhile.

Why 90%, you may ask? In fact, 90% is completely arbitrary. It turned out, though, to be a sensible threshold which gives reasonable numbers.

Where are my toons stored?

This site uses the latest HTML5 features to store all your toons locally on your computer or mobile device.

This has quite some advantages:

Usability: No registration is required. Just get started by specifying a rod and a toon name (so that you recognize it later on – you can also make up something here).
Privacy: you have full control over your data.
Economy: no database is cluttered with unused or forgotten data.
Coolness: HTML5 is just awesome!

Unfortunately, there is a downside (there always is).

All data remains within the browser you are currently using. You cannot access it on other devices or browsers.

You can, however, transfer all your stored data to another device – just click the „Export toons“ button on the toon management page and follow the instructions.

That way you can also create a backup by storing the link that is generated there, into your bookmarks.
