Do Golems and Lava Hounds return to the Clan Castle if Golmites or Lava Pups survive?
If your clan castle troops survive an attack they will return to your clan castle at full health. Do Golemites and Lava pups count as a Golem or Lava Hound surviving?
According to the Clash of Clans wiki:
If you have a Golem in your Clan Castle, and it splits into Golemites during a defense, it will become a Golem again after the defense if at least one Golemite survives the battle.
(Golemite Page)
So Golemites will return as Golems if at least one survives.
I could not find any sources for lava pups, however I assume they would behave similarly.
