Fusing[edit | edit source]

Fusing is a part of zoo that makes you gain a passive currency called Zoo Tokens™ by temporarily sacrificing your animals. You can fuse with $ fuse [animal]/[animal]

Fusing requires two animals. In between each fusion there is a cooldown that changes based on which rarities you fuse. You cannot fuse the same animal.

Additionally, Fusion skips confirmations when the ! character (exclamation mark) is put at the end of the command. (e.g. $ fuse dog fox!)

Rarities Zoo Token™ per rescue Fusion Cooldown
Common / Common 1 2 rescues
Common / Rare 3 4 rescues
Rare / Rare 5 6 rescues


For every 200 Zoo Tokens™ per rescue, the fusion cooldown will increase by 1 rescue.

Fusion cooldown is applied first, then the total Zoo Tokens™ per rescue. For example, if you have 199 Zoo Tokens™ per rescue and you fuse 2 common animals, your fusion cooldown would still be at 2 rescues.


Fusing animals will remove them from your inventory and lower your score. However, you can unfuse the fused animals at any time, giving you back the animals and zoo scores.

Some fusions have unique names.

Animals Name
Peacock + Cockroach Cock²
Bear + Polar Bear Slightly Less Polar Bear
Snowier Man + Snowman Snowiest Man
Jellyfish + Fish Jellier Fish
Bactrian Camel + Camel Pregnant Bactrian Camel
Dinosaur + Fish Sacabambaspis
Horse + Chick Umamusume

Zoo Token™[edit | edit source]

Zoo Tokens™ are passively generated from fused animals. Every time you rescue, a certain number of Zoo Tokens™ are generated, which depends on your Zoo Tokens™ per rescue.

You can't generate more than 9999 Zoo Tokens™ in a single rescue

Zoo Token™ is the currency for The Token Shop.

Zoo Token™ is counted as a special item. It can be viewed using /items, but is not counted towards total item and is not counted as a unique item.  

The Zoo Token™ looks like this:

NFB[edit | edit source]

NFB, which stands for Non-Functional Beasts, increases the rate of your Zoo Tokens™ per rescue. The rate increase can be stacked.

A common NFB will increase the rate by +0.5%, while a rare NFB will increase the rate by +2.5%.

NFBs are acquired using using Base Mystery Egg, Golden Mystery Egg or Blank Mystery Egg.

NFBs bonus caps at +1000%

The names of NFBs are composed of three parts. An adjective is always in front, followed by an animal, and finally a hashtag with a 6-digit number.

NFBs can be viewed using $ nfbs. However, they cannot be sorted. Your most recent NFB will always appear at the end of the list.
