I think they initially sealed Kaguya into Hagoromo. Then as Hagoromo was dying, he split the chakra into the 9 tailed beasts which left the gaduo mazo thing that I can't spell (Ten Tails shell thing). He sealed the geduo something into the moon using Chibaku Tensei. Which obviously he could do himself, if he gave the seals to Sasuke and Naruto to do it.
