Just as the monsters were phasing out production of the old mines, they stumbled upon an immense underground vault containing several of the mysterious objects known as the Wubbox. Very little is known of their origin or purpose, save a few observations:

After being incubated in the nursery, sample analysis of the box's exterior indicates that it shares traits with every known monster species - in fact, it even has specialized compartments with an otherworldy shrinking technology. The box is also imbued with an elemental energy unfamiliar to those on the surface - a shocking discovery, to say the least.

Gather some intrepid monster volunteers and see what happens when you 'box' them!

~ Inactive description
Eureka! The Wubbox awakes!  As it turns out, this extraordinary electric elemental is vital to the life processes of the colossal island monsters that the other singing denizens call home.  The shrunken monsters used to power up the creature report that inside is as fun as any playground they've ever seen, so they are happy to stay indefinitely.

The robotic chirps and whistles it uses to express itself can take some getting used to, but eventually become a beloved and inextricable part of the island's tune.  Besides, it's all the rage in "current" music.

The specific breeding characteristics of the Wubbox have not yet been studied.

~ Active description


When first placed on an island, the Wubbox is a box that does nothing until you box (feed it) one of every monster that exists on that island (except Seasonal Monsters, Ethereal Monsters, Legendary Monsters, and Rare Monsters). This requirement can be bypassed by the use of diamonds - 450 Diamond25px is required to activate a fresh Wubbox, but this cost is reduced by 30 Diamond25px for each monster placed inside. When the collection is complete, it turns into a singing and dancing robot that can be fed to increase its levels, has likes to improve its happiness, and earns coins like a normal monster. Only one inactive Wubbox may be placed on any one island at a time.

Boxing monsters

Once a Wubbox is placed on an island, when another placed monster is selected, an additional option to Box that monster appears. Additionally, in the Nursery, a third option shows up after you place the Wubbox, so now you can Place, Box, or Sell. Thus, monsters can go straight from the nursery into the Wubbox without being placed on the island first.

After a monster has been boxed, it doesn't count towards the happiness of other monsters, even with the help of a Unity Tree.  For example, suppose you have a Ghazt on Plant Island that's at 100% Happiness, in part because you have an Entbrat there as well.  But if you Box that Entbrat, your Ghazt's Happiness will go down to 75%.  You would need to get another Entbrat to restore the Happiness of the Ghazt.

For most intents and purposes, once a monster has been Boxed, it is gone.  It doesn't generate coins, and it doesn't make other monsters happy.  If it was at Level 15 and had appeared on Gold Island, Boxing it on its natural island will make it disappear from Gold.

Gold Island Activation

Once the Wubbox is leveled up to level 15, it can be placed on the Gold Island. Once placed on Gold Island, it becomes a box again and requires one of every 'regular' monster type (that is, not the limited edition monsters or rare monsters) available on Gold Island. The Wubbox remains active on its original island - remember the Gold Island is a different dimension. Again, only one inactive Wubbox may be placed on Gold Island at any one time.

In order to box monsters on Gold Island, they must be placed on the island - unlike the Nursery, there is no option to do it from the list of unplaced monsters. This is not an issue for bed management, since Gold Island has unlimited beds, but clearing the physical space for monsters on very crowded and populated Gold Islands could be a concern.

Just as any monster placed in the Wubbox is removed from their island permanently (and on Gold Island) - Gold Island monsters placed in the Wubbox are also removed from Gold Island (and their home islands).

If the Wubbox is removed from Gold Island and then re-placed once more, it returns to its inert box form, and must be activated again. As for the other islands, the Wubbox activation may be sped up using diamonds, though each monster missing costs 300 Diamond25px, for a grand total of 9,000 Diamond25px for a fresh Wubbox.

Ethereal Island Activation

The Wubbox may also be found on Ethereal Island, but it must be purchased from the market rather than teleported from another island. Alone among all the other Wubbox, activating the Ethereal Island Wubbox requires feeding it Ethereal Monsters, one of each type that exists on the island. As with other islands, the Wubbox activation may be sped up using diamonds, though each monster missing costs 800 Diamond25px, for a grand total of 12,000 Diamond25px for a fresh Wubbox. Fortunately, recently hatched Ethereal monsters may be boxed, unlike Gold Island.


The Wubbox is a monster species different from every other in many ways.

After its egg is hatched, the monster turns into a big and ornate yellow box with a huge red button on top, that appears to have a door on its visible face, complete with small stairs. Near the "door" there are strange, otherworldly patterns shaped like swirls and dots. On the back of the box are three pistons.  In this dormant phase of its life cycle, it appears to be snoozing, like monsters that have been Muted - little "Z"s stream upwards from it.

After undergoing the unique feeding process that defines its species, it will transform: the Wubbox is the only monster who passes through huge changes after being born. 

It now appears as a giant, yellow, humanoid robot, the tallest monster in the whole game, ready to be fed like any other monster is.

This robot has a big spherical power core suspended in the center of a gap in the middle of its body.  The sphere glows blue-white, but it's insubstantial; one sees the background through it.  From time to time, the power sphere pulses, or swings in a figure-8 around and through the Wubbox.  The robot's limbs have multiple segments that appear to be connected by nothing more than brilliant electric arcs.  (Some mysterious force fields may be at work here.)

Its hands are like huge iron bolts with fist-like structures on top of them, and its forearms, yellow like its body, have blue swirl and dot patterns that resemble the ones it had while in its box form, now powered up by the electricity.

Finally, it has a face with a big mouth and teeth, and metal cups supporting large red-and-white eyes with red lids. Its eyes occasionally flash.  There is no head visible apart from the mouth and eyes; its neck consists of multiple cylindrical segments with no visible connection.


Audio sample:

The Wubbox's tune is a loud and vibrant electronic dubstep that makes a big difference to the song of the island it is in.

When not playing its dubstep (not muted though) it will still make other sounds, listen closely! The Wubbox may sometimes fist-pump to make a brief hi-hat cymbal sound, jump to make a thump, or swirl its orb around to make a synthetic sound.

In the Gold Island, the tune is shorter and becomes more harmonious with those of the other monsters. In Ethereal Island, the Wubbox plays only once in the whole song.


The Wubbox cannot be bred; it can only be purchased in the Market.

Earning Rate and Maximum Income

Earning rate is in coins or shards per hour and depends on Happiness % (Likes increase Happiness), also each monster has a limit to how much income it can hold at a time. Increasing the monster's level increases the limit. Earning rate is in coins per minute, for an Activated Wubbox only (until fully "fed" it produces nothing except ZZZ's).

Feeding Monsters

Each monster needs to be fed four times before it reaches the next level. Increasing the monster's level increases the coins earned per minute, as well as the maximum coins earned.  The food per level is the same as for Ethereal monsters, and can be found in this article.


  • ToobGo to Toob
  • DiggerGo to Digger
  • Ambered ThingGo to Ambered Thing
  • Tub FountainGo to Tub Fountain

Every monster has different things that they like. For every unique object that they like that's placed near the monster, the monster's happiness will increase by 25% (in other words, placing two of the same liked item near a monster will still only increase happiness by 25%).

See the Likes page to view a complete list of all monsters' likes.


Some items to take into consideration when designing your island by strategy are number of beds for the monster, rate of income per bed, max income per bed, and time for max income to be reached.  The income below is for level 15:

Coins Shards
Number of Beds 6 15
Rate of Income High 360 108
Rate of Income Low 180 54
Max Income 518,400 518
Rate of Income per Bed High 60 7.2
Rate of Income per Bed Low 30 3.6
Max Income per Bed 86,400 34.5
Time to Max Income @ High 24:00 hours 4:48 hours
Time to Max Income @ Low 48:00 hours 9:36 hours

Name Origin

"Wubbox" is a possible junction between the words "wub", (an onomatopoeia for some dubsteb sounds, referencing the creature's music) and box (due to the monster's unique post-hatching behavior).

Rare Version

Rare Wubbox

Rares are special versions of monsters that are only available to buy and breed during certain events. The breeding combination is the same as a regular monster, but the breeding time is longer, the "likes" are different, and the earning rates are higher. They are not yet available in the Windows version of the game.

Find out more about the rare version of the Wubbox on the Rare Wubbox page.
