Twins

According to the Matope main thread, during any breeding there is a 50% chance for a second sac, and then a 10% chance for it to contain twins. Twins are identical kimeti, with on being male and one being female. The goo color for a twin sac is purple.

Some kimeti look identical, but may or may not be twins. They could have been colored identical for a matching event. In any such case, the owners would decide their twinhood or lack thereof.
