I thought it was just two? And the males have matching anatomy?
Three for the females combined with 2 uteri. (same for Wombats and Tasmanian devils)
Males often have two penises, and to continue the the strangeness, the testicles are above the penis(es).
Females can have two embryos at different stages of development and can stop and restart the development. Perfect adaption to a harsh climate, allowing them to time the Joeys arrival when there will be food. Males have the extra adaption, big Roos can cover 6 metres (20 ft) each hop.
