My Singing Monsters

MSM Bio:

The T-Rox exudes enthusiasm and energy, displaying flashing spikelets and chomping jaws. Monsters with toes should steer well clear of the T-Rox.

MSM Composer Bio:

The jaws and feet of the T-Rox have almost seismic power, producing crisp, resonant beats that are reminiscent of an electric drum kit. Its syncopated performance is almost akin to a dance.


The T-Rox bears a strong resemblance to the large carnivorous dinosaur, Tyrannosaurus Rex (which is often abbreviated to T-Rex). Its body is constructed out of gray stone with two clear blue crystal horns, and two clear blue crystal spikelets visible along its tail. Its bright yellow jaw and feet appear similar to scoops commonly seen on ditchdiggers.

When this monster is idle, it stays in tempo by enthusiastically swaying or rotating back and forth.

The T-Rox Monster's contribution to an Island's song is akin to synthesized drumming. The Monster's pounding feet produce an electric bass drum sound, while its chomping jaws sound like an electric snare being struck.


The T-Rox can be bred using monsters that combine to provide the elements of Earth, Water and Cold. Possible combination(s):

Because all of these two-element monsters take the same time to hatch, these combinations all take the same amount of time when they don't produce a T-Rox.

Earning Rate and Maximum Income

Earning rate is in coins 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.

Every monster has different things that they like. For every unique object that they like that's placed near the monster (if not using a Unity Tree), the monster's happiness will increase by 25%. Placing two of the same liked item near a monster will still only increase happiness by 25%. Below are the things liked by T-Rox:

Wublin Egg Consumption

While trying to breed other monsters (particularly monsters with a very low chance of breeding), the following Wublins can be used to "dispose of" T-Rox eggs immediately instead of putting them into a Nursery and having that Nursery not be available.

Note that bred monster eggs can only be "disposed of" into inactive Wublin statues; active Wublins do not accept monster eggs. Also note that inactive Wublin statues to which you have already disposed the number of T-Rox eggs that Wublin accepts, will no longer be available as a "recycle bin" for such eggs.

Celestial Egg Consumption

Name Origin

T-Rox is most likely is a portmanteau of the words T-Rex (Tyranossaurus rex), a Dinosaur from the cretaceous period, and "Rocks", probably because the monster has rock-like scales over its body.

Halloween T-Rox


During the Halloween season of October, all T-Roxes (on all the islands) dressed up as green dinosaurs, a real T-Rex, or a Zombie T-Rex as part of the Plant Island Halloween celebration. It is not known for sure which, because they all have a green body, white sharp teeth and claws.

This costume did not appear in 2015.


  • Whenever the T-Rox chomps, the crystal horns and spikelets on its tail light up.
  • The name "T-Rox" remains the same in almost every translated version of the game. 
  • The T-Rox is the only triple element monster that does not require 12 hours of breeding/incubating. This is particularly useful for breeding the ethereal Ghazt and Reebro on the Plant and Air islands.
  • T-Rox has the elements earth, cold and water but cannot be placed on earth island, cold island or water island.
  • Despite the fact that T-Roxes only finish being bred/incubated in 8 hours, it still has a higher maximum coin income compared to the other three-element monsters in Plant Island.
  • As with the Maw, Scups, Entbrat and Mammott, there's a concept drawing of the T-Rox.
  • The T-rox's feet look similar to the Digger decoration.
  • One of the T-Rox's default names, Toebegon, is a reference to its bio, which hints that its stomping can cause great damage to toes.
  • Despite its bio mentioning that "Monsters with toes should steer well clear of the T-Rox", the Congle likes the T-Rox (the Congle has toes).
  • The T-Rox and the Stogg are the only two monsters with dinosaur-like features.
  • In the files, the T-Rox is referred to as "Rockstomp". This may have been its beta name.
