That's the MatchMaker. See, the MatchMaker comes when your Tama hasn't found a mate/partner/wife or husband and she finds one for you!
Then, the adult Tama will stay on the ground and look after the baby. You only have to clean up the baby's poop and take it to the Hospital when it gets a Toothache or is Ill. You still look after your adult Tama like normal, playing games, feeding it, the normal stuff. Your adult Tama will eventually die, or go back to it's planet, and then you'll have to look after the baby! You MUST tend it's every need!!!!
If you pause your Tama a lot, then when it's still young, sometimes, the MatchMaker comes!
That should put an end to your worries, I hope!
