    You wanna bred all 4 different kangaroos and their color variants for this one, by doing this you get also the other Australian bred achievement for breeding all the kinds of Australian animals.

    You can get this in Free or Challenge mode, i recommend doing it in Free mode because you have unlimited money to spend etc..


    Build 4 big/medium Australian outback's.

    Adopt in every outback a different variant of Kangaroos, if you build a big outback(10max) you wanna buy 3male and 3females, and medium outback(6max) 2male 2female.

    Make your animals happy by buying food, wash stations and something to play with, it need to be for kangaroos (3stars), hiring zoo keepers will help also.

    Then build a breeding facility and employ 4 people, then assign them to the 4 Australian outback's.

    Then just wait..

    If you don't get a color variant right away you can sell or donate it, or release 2 adults in the wild, 1male 1 female ofcourse..

    brayargYou should mention that you can research both increase Breeding chance and increase skin pigment chances via selecting the park entrance and going to research. I think it's the 2nd or 3rd option from top... research times are 30 seconds, 1 minute, 1 minutes 30seconds. 3 levels. Highly recommended to do as I think the bonus for skin pigment is 50% increase chance.

    GerbasgamerIf you play in free mode as he suggested you don't need to manually upgrade anything.

    venksbondFor me breeding starts (dec 2020) only with large outback not with medium in sandbox mode, initial 15+mins I spend time to get 4th kangaroo on level 20.

    So I would like to suggest keep building little things(entertainment/drinks/facility) then build large outback but dont keep animals now. Once u can build breeder centre keep making it load staff, level up them & assign to outback until you reach level 20.

    If you put animals before level 20 u will waste time in cleaning poop. If u make dirty they wont get pregnancy quickly

    Now keep animals 6(3m,3f) with level >9+2 kids and put double grass this way pregnancy is much quicker in another 5mins u will get achiv. For me it took 40mins(20 mins wasted for medium).
