Idleon has added companions (sometimes referred to as pets or followers) which give various bonuses to many aspects of Idleon, ranging from mediocre to absolutely overpowered boosts.
These companions can be unlocked from World 1 town and you can get one random companion for free every week.
The main negative aspect of these companions is that you can only buy them using Green Gems, which are only obtainable through paying real money for them.
Even with the new Trade System, you can only trade pets that you purchased using Green Gems.
So how exactly do these companions work and are they worth the trouble?
Fallen Spirits Update!
We’ve added the new Fallen Spirits Companions and Exclusive Companions to the guide and added an explanation on how the Trading System works.
How Companions actually work
You can open the pet management map by clicking on the Doggy in World 1.
He will transport you into a map where you can see all your pet companions and unlock new ones.
There are currently 23 different companions available (and 3 paid ones you can only obtain through bundles). You can choose between Legacy Companions or Fallen Spirits Companions.
You get one pet for free every week, and you can choose which collection to get that pet from, by clicking the button below to switch between views.
Legacy Companions
For Legacy companions, you must pay an increasing amount of Green Gems to increase your odds of the next pet.
Each pet has a certain chance to be unlocked depending on the usefulness of their bonuses.
There are 5 tiers of treats, which increase after a few pet purchases, increasing your next pet odds.
The tiers start off at Tier 1 with x1 odds and maxes out at Tier 5 at x3 odds. You will reach Tier 5 after buying 38 pets for a total of 5,660 pet crystals.
To get the rarest Legacy Companion, King Doot, you have a 0.85% chance to get him when your odds are maxed out.
Buying 200 Legacy pets guarantees King Doot as a reward.
Note!
Once you reach Tier 5, you will have a 0% chance to get the white-tier lowest companions, so make sure to keep one of each to get their bonuses, or you will have to trade with other players for them.
The cost of unlocking a pet also increases every time you reach a new Tier (but your weekly free unlocks also get those higher odds), going all the way up to 250 Pet Crystals at Tier 5.
The animation at the top doesn’t affect your results, but you do need to wait for it to finish every time you buy a new pet.
Fallen Spirits Companions
The new Fallen Spirit companions work a little differently from the Legacy ones.
Instead of buying treats to slowly increase or odds permanently, you get to choose which treat to buy directly, with higher odd treats being more expensive.
While with Legacy pets, buying any pet will increase your guaranteed Doot counter towards that 200 limit.
However, with Fallen Spirits, each treat has their own limits for guaranteed pets (basic treat has no guaranteed extra rewards). Each treat has their own caps, so buying Nice Treats for example wont count towards Deluxe Treat guaranteed rewards.
| Treat | Amount you need | Possible Guaranteed Reward |
|---|---|---|
 Basic Treat | – | – |
 Nice Treat | 10x |    |
 Tasty Treat | 20x |   |
 Deluxe Treat | 30x |  |
The good part about this system is that you can target specific companions better, if you’re missing a specific rare companion like Jocund or Samurai and it will cost a lot less to get a guaranteed Ancient Golem than it would for a King Doot.
Recycling Companions for Green Gems
Having a single copy of each pet is enough to get their respective bonuses so you can Recycle any duplicates.
Recycling a pet will give you back some Pet Crystals depending on that companions rarity, starting from 5 all the way up to 2,000 Pet Crystals if you recycle the rarest pet.
You get 0 Pet Crystals for recycling a free pet, so they can’t be abused by creating many accounts.
You get ALL the bonuses for ALL characters at ALL times for every unique pet that you have unlocked.
Having multiple copies of a single companion has no use, so you can save them to trade with later, or recycle them to get a few gems.
All Companion Bonuses and Odds
Companions have two different views and you can toggle between them to unlock pets from a certain set, but they will all stay active at all times once you unlock them.
You can check the table below to see all the currently available companions.
Don’t save your weekly free pet unlocks, as they don’t stack!
You can find all the Tier requirements at the end of this article.

 King Doot | 0.28% | 0.85% | 2,000 | All Divinities from World 5 active for all characters! (This includes both Major and Minor bonuses) |
As you can see, the rarest pets are extremely rare and their bonuses are extremely powerful, which is why this update has caused a lot of anger among the Idleon community.
Also some players have noted that the Purrmep Divinity doesn’t work properly if you don’t have one character linked to it, even if you have King Doot, so make sure to link one to it just in case.
Fallen Spirits Pets
| Companion | Recycle Reward | Bonus |
|---|---|---|
 Green Mushroom | 5 | +15% Accuracy |
 Quenchie | 5 | +15% Drop Rate |
 Poisonic Frog | 5 | +15% Defense |

The Deluxe Treats for Fallen Spirits will increase your odds by 15x so it is easier to get these rare pets and as you may notice, they’re again very powerful, especially Samurai and Ancient Golem.
Exclusive Pets

|---|---|---|---|
 Mallay | – | Available to buy during the 4th Anniversary Event for $19.99 (uncertain if they will be available later) | 1.30x Drop Rate |

 Cool Bird | 500 | Same as above | 4x Coins from Mobs |
 Glunko Supreme | 500 | Only available as a reward from the Developer during certain Discord events. Unobtainable normally. | No effects, just cosmetic |
These are purely Pay To Win pets (and fairly expensive at that), but they provide insanely huge bonuses.
Legacy Pet Treat Tiers Explained
Buying a Legacy pet is referred to as buying a treat, after which a pet comes to eat said treat.
Once you buy enough treats, you upgrade the Treat Tier which gives you higher chances to get a better pet.
Below you can see the requirements for each tier and what odds each tier gives.
| Treat Tier | Pet Odds | New Pet Price | Pet amount to unlock | Total cost to unlock |
|---|---|---|---|---|
Broccoli (Tier 1) | x1.00 | 100 | 0 | 0 |
Canned Fish (Tier 2) | x1.25 | 120 | 5 | 500 |
Chocolate Coin (Tier 3) | x1.60 | 150 | 13 | 1,460 |
Ice Cream Sandwich (Tier 4) | x2.00 | 180 | 23 | 2,960 |
 Jawbreaker (Tier 5) | x3.00 | 250 | 38 | 5,660 |
As mentioned earlier in the guide, make sure to get at least one of each low tier pet before going to the highest tier, as you will have 0% chance to get the lowest pets at that tier.
Pet Trading System Explained
The Companion system now includes the ability to trade pets with other players and it’s a huge addition to the game is it makes it a lot easier to get those missing pets.
You can only trade pets that you have purchased with Green Gems, however once you trade any pet, it will become locked but you get to keep the original pet AND the pet you traded it for.
The only difference is that your original pet becomes locked, so you can’t trade it multiple times and can’t Recycle it for Green Gems.
In order to trade, you must first select the pet you want to trade as a Follower. You can do it from the button next to the Recycle button and then click on the pet you want to set as a follower.
Then double click on the person you wish to trade with and click the Trade button.
After that, a trade request window pops up and you must confirm that the trade is what you wish to send to the person.
Finally, the other person you are trading with must go to the Doggy NPC in World 1 and accept the trade.
As you see, the process is very simple and if you are good at begging, you can even get people to donate their pets to you for nothing in return.
This means, in general you should not turn your good pets into gems, but try to trade them into something you are missing instead.
