I made two sets of experiment to feed my curiosity about monster breeding. The finding was quite fascinating and i want to share it with you. I hope this section will answer most questions about monster breeding. The experiments was involving Chubby Gloop, Peep-Eyed Gloop, and Boxy Gloop. I used my Chubby Gloop to produce fifteen eggs each from Peep-Eyed Gloop and Boxy Gloop making the total of 30 eggs. The maximum number of eggs that incubator can handle is 10 eggs so every time my incubator full, i had to discard and gave away some Gloop eggs. Also, each monster can only produce 3 eggs maximum so i need to give it Star Sparkles to produce more eggs. Sounds mean isn't it? Forcing a being to keep reproducing...
The first set of experiment was to breed my Chubby Gloop with Peep-Eyed Gloop. From fifteen eggs they produced i got: 3 Peep-Eyed Gloop eggs, 11 Chubby Gloop eggs, and 1 Boxy Gloop egg (the 3rd egg). I kinda suprised that breeding can produce new sub-type of monster even though the percentage was really low. From this result i decided to continue with another eperiment.
The second set of experiment was to breed my Chubby Gloop with Boxy Gloop. From fifteen eggs they produced i got: 6 Chubby Gloop eggs, 6 Boxy Gloop eggs, 1 Peep-Eyed Gloop egg, and 2 Squiggly Gloop eggs (the 2nd and the 8th egg). From breeding Chubby Gloop and Boxy Gloop, another new sub-type of monster emerged.
The image below help summarising the breeding result:
A+A = A 90%; Others 10% or maybe less. (also applied for B,C and D)
Apparently breeding same sub-type of monster could result in different sub-type of monster! One Monster Pet Shop fan, Habona, tipped me about this information. Driven by curiosity, i decided to take another experiment. Since im about to run out all of my Monster Berries, i ask my wife nicely to do the experiment for me (yes, my wife plays MPS). She did A+A and the result was not A. Could be B C or D.. We don't know yet because we have not incubate the egg.
A+B = A 20%; B 73%; C 7%
B+C = A 7%; B 40%; C 40%; D 13%
In conclusion, breeding different sub-type of monsters could produce a new sub-type of monster. The only problem is, the chance is fairly low.
NOTE: Those figures are based own my own research. There is a high probability that you will get different results. Feel free to conduct your own experiment.
SOME OTHER INFO ABOUT BREEDING
LUCK
When it comes to breeding, luck plays important role. Sometimes you will find yourself in a good situation where you only need just one try to get an egg from your monster. But OFTEN you will find yourself in unfortunate situations where you need several tries before you get just one egg. There is no formula to get an egg in one try. This is why breeding can be a very tricky and costly thing to do.
MY MONSTER WON'T BREED
You have three breeding partners to select for you monster. However, if none of them want to mate with your monster, you need to try and try again. It doesn't matter if you choose the same or different breeding partner for each try because eventually you will hit a success. You need to spend a certain amount of gold for each try. That is why breeding can be costly.
You can also perform in-house breeding for your monster if you have two monsters with the same type (regardless sub-type) at your shop for free.
COLOUR RESULT
New egg from breeding will have the same colour as it's parents. Lets say you breed PINK monster and ORANGE monster, there is a fifty-fifty chance that you will get PINK or ORANGE egg.
