Yes not all of these are complete but if you can notice it's from that one gay short film with the heart.

This is Sveltlana, so I found out there was 2 tortoises who went to space and orbited the moon. So she's based off of that.

And so is Charlin.

This is the two of them, the spacecraft the two turtles were in were from the Soviet Union so yes they're Russian...
